    Apparently macOS Ventura, iOS 16.1 and iPadOS 16.1 will be released
    followed probably by all sorts of new hardware in the next few weeks. I’ve been running Ventura beta for a while now so I sort of know what to expect!

    iOS 16.1 has this: “A new clean energy charging feature will "optimize" charging times to when the grid is using cleaner energy sources."

    How can that possibly work?

    Fortunately it can be turned off, along with the current “optimized charging”. When I plug it in, I want it charged as fast as possible. I
    am not interested in waiting until Apple decides “now is a good time to charge your phone”. 🙄

    I wish the stupid changing volume up/down buttons could be turned off on
    the iPad Mini 6. “Fixed Position Volume Controls” is NOT a setting on the Mini 6. It is on every other iPad I have, and it is on. The Mini 5 has
    this, but not the Mini 6.

    This is the most annoying “feature” I have ever seen. The iPad can by laying flat, but it decided to rotate on the way to being laid down. So
    the volume buttons are backwards.

    I'd be surprised if it does work in the UK, but it'd be quite straightforward to determine when, say, wind, is providing a decent amoutn of energy and ramp up the charging rate then.

    Fortunately it can be turned off, along with the current “optimized charging”. When I plug it in, I want it charged as fast as possible. I am not interested in waiting until Apple decides “now is a good time to charge your phone”. 🙄


    If you're in no rush (most of the time I'm not) I can't see what harm it does
    - and it may do a lot of good.

    How can that possibly work?

    Some energy suppliers *do* report that information, and EV SEs
    (colloquially called car "wall chargers" except the charger's actually
    in the car) can query them to do a similar sort of optimization. Ohme's probably one of the most popular chargers to do this.

    So it relies on the suppliers providing some sort of network API, and
    for Apple to call them.

    Or more locally, if your house had solar panels (maybe with battery
    storage) as well as a grid connection, you could query your "box" to
    only run when you've got solar (or stored solar).

    It is all doable. Energy systems are getting smarter, and kudos to Apple
    for joining in.

    So recharging some phones and things over solar won't make much
    difference by itself, but start aggregating all these things recharging
    and it gets much more interesting.

    You'd have no way of really knowing how the electricity you are using is being produced unless
    you know where it is being generated from and who by, which I though was inpossible to know
    from a 'national' gride.

    Indeed I am. Seems pretty successful here on my old iMac, which is
    running macOS 12.6.

    FYI, it's a Late 2013 iMac 27" with Nividia GPU (Kepler), it seems the
    Kepler is a bit of a stumbling block, but I usually only have a wait a
    bit longer for OCLP to get an update for it.

    As far as I can see, there have been no untoward issues, it's as stable
    as it's ever been. Even things like Universal Control have worked fine.

    For anyone with an older machine, and can afford for this to not work
    out too well, it's certainly worth having a go.

    Not too sure if I'll risk MacOS 13 yet, but it would be handy to make
    use of the Shared Photos Library across all devices.

    local refinements later.

    And yes, I know, iPhones are irrelevant, energywise.
    Applying the same ideas to electric vehicles will make a difference.
    Look at it as a pilot study for technology development.

    Solar is a bit disappointing.

    At these latitudes, solar is a poor use of resources. Especially in winter
    when there are periods (lasting up to a week or more) with high pressure, causing wind output to be close to zero, and if it is overcast then solar is also zero. Such high pressure areas can cover most of Europe.

    We should have had a big push for nuclear when North Sea gas was at its peak, knowing it would run out, and thereby having some future-proofing. Renewables are a poor investment as you end up paying twice for the same power output.

    Solar is a bit disappointing.

    At these latitudes, solar is a poor use of resources.

    Something that pays for itself in five years cannot be
    'a poor use of resources'.

    Especially in winter
    when there are periods (lasting up to a week or more) with high pressure, causing wind output to be close to zero, and if it is overcast then solar is also zero. Such high pressure areas can cover most of Europe.

    For the forseeable future there is not shortage of gas
    for backup purposes.
    No doubt there will be storage solutions for the longer term.

    But the iPhone really is a nice pilot project.
    In the future we can expect to see electric vehicle batteries
    used for storage, by charging and discharging into the grid
    on instantaneous demand.

Renewables are a poor investment as you end up paying twice for the same power output. See my comment above: when renewables produce nothing, you have to have backup.

    Nuclear is completely unsuitable for a backup,
    because it cannot be regulated.
    It must be on at near full power all the time.
    But you are stuck with it,
    because you allowed EDF to swindle you into rescuing them,
    with some help from the Chinese.
    You are stuck with lots of far too expensive power generation.

    Yes I can appreciate that but I was trying to make the point (not very
    well), there's a lot more that can be done on a smaller scale to offset
    the drain on electricity grid systems, e.g. Solar panels, small wind
    turbines systems etc.

    Small wind turbines just are not cost-effective.

    Incidentally wind turbines don't have to use giant
    propellors - they could be horizontal screw like devices mounted on top of office blocks, barns, even large houses etc. with much less visible
    impact.

    Yes, I have seen some of those.
    (including a big horizontal Darrieus rotor on a rooftop)
    They were definitely not a succes.

    There is nothing that can beat the efficiency of a big propellor.

    That is not the reason for the efficiency of larger rotors. It is the
    higher rotor area and the cost degression of longer blades. The high
    speed tips are in fact reducing the efficiency.

    We should have had a big push for nuclear when North Sea gas was at its peak,
    knowing it would run out, and thereby having some future-proofing. Renewables
    are a poor investment as you end up paying twice for the same power output. >> See my comment above: when renewables produce nothing, you have to have

    Nuclear is completely unsuitable for a backup,
    because it cannot be regulated.
    It must be on at near full power all the time.
    But you are stuck with it,
    because you allowed EDF to swindle you into rescuing them,
    with some help from the Chinese.
    You are stuck with lots of far too expensive power generation.

    It's the best low carbon electricity source for baseline generation. Like
    you say it's best running at full power which is exactly what baseline
    needs.

    Oil and gas is only going to get more expensive and renewables aren't
    reliable enough.

    At these latitudes, solar is a poor use of resources.

    Something that pays for itself in five years cannot be
    'a poor use of resources'.

    Especially in winter
    when there are periods (lasting up to a week or more) with high pressure,
    causing wind output to be close to zero, and if it is overcast then solar is >> also zero. Such high pressure areas can cover most of Europe.

    For the forseeable future there is not shortage of gas
    for backup purposes.
    No doubt there will be storage solutions for the longer term.

    So we build two power stations to get the output of one. That's clever economics, top be sure.

    [1] In actual operation you start pumping out water before low tide.
    (and continue past low tide)
    You let it in again at mid-tide, and start pumping in before high tide.
    This is both energy amplification, and pumped storage.

    There was a scheme for tidal power in the Severn

    At times when the spot price of solar and wind

    because you cannot turn off, or even down, the nuclear. [1]
    This violates the basic economic principle that marginal kWh-s

    This is in effect a huge hidden subsidy for nuclear,

    Jan

    [1] Even nowadays the electricity price already goes negative
    when there is a strong wind on the North Sea.
    This will happen more frequently in the near future,
    given the huge planned increase in installed wind power.

    But therein lies the issue. This is more than an economic matter. Add the social, political and environmental gains, monetise those (if you must), and then reappraise.

    High and Low tide times vary considerably around the UK coast. With careful station placement surely some tidal power would be generated 24/7. Not

    The suggestion was the Severn. There's no equivalent sized other site with the correct phase difference, elsewhere, to match its output. Even then, if there were, you'd need to turn the grid away from a load balancing and into a distribution network. It'd need to be a lot larger to cope.

    And every little does not help. It distracts from what we should be doing, which is building reliable nukes for our caseload. Baseload which will get a lot larger if we start having large numbers of electric cars.

    Large Tidal Power Stations are in operation since 1966. The high
    predictability makes this form of electricity generation very attractive
    and useful:

    Thanks both of you.
    I had no idea that there was that much wind power installed already.
    (with very little of the potential area used yet)
    Solar is a bit disappointing.
    There must be many square kilometers of unused roofs.
    At todays prices the pay back is only a few years.
    Also nice to see that you are feeding France,
    with their non-functional 'nucleaire'.

    I suspect the -ve values actually mean imports. We typically buy
    electricity from France




    We also export electricity to France at appropriate times. It's the
    strongest practical argument for not synchronising clocks with Europe,
    that one hour difference in peaks is very useful.

    AFAIK abolishing Greenwich time has never been seriously considered.
    (exept as DST)

    It has been suggested often, masked as remaining on BST all year round
    rather than put the clocks back in winter. Winter, of course, being the
    time when the hour's difference between us and France is most useful.

    As a matter of historical interest, the opposite has happened.
    Before WWII France had Greenwich time. The Germans changed it,
    and after the war France didn't change back.

    High level waste such as spent fuel rods is store din large water tanks for some years (such tanks are even safe to swim in as long as you dont' dive down to the rods). Intermediate level waste is vitrified, a process that is
    routine. Low level waste can essentially be ignored.

    People wet their knickers far too much about this issue. Life has been dealing with radiation since it emerged on the planet and by and large deals with it. Your body experiences 4000 radioactive decays every second (mostly K-40) throughout your life, and this is nothing new.

    Over 100 %, actually.
    But burning gas for just heating is a very bad idea too.

    In the sense that one could use it to generate electricity while taking advantage o the heat, I agree that is true. How about a tiny gas
    turbine in every home to generate heat, and export electricity in the
    same was as is done with solar panels?

    There is already a system for producing methane: it is called a sewage
    treatment plant.

    There is also an enormous amount of biological material which could be
    added to sewage to increase the amount of methane generated. For example: >>
    • wood waste from building and industry;

    • domestic kitchen and garden waste;

    • material from agriculture such as animal manure, straw and the like
    from grain crops, culled animals, abattoir waste;

    • industrial food processing waste;

    • as well as human cadavers (which might otherwise be incinerated at a
    cost of about 240kg of CO2 each).

    All quite limited resources.

    But all are renewable, although at present agriculture relies on fossil
    oil for its fertiliser and fuel for machinery.

    Have you any figures to suggest whether waste biological material would
    be sufficient to make a useful contribution? Or would it be best to
    regard it as an easy way to clean up the environment, particularly of
    unsightly and damaging platic waste?

    Assuming we can produce lots of electricity by various green means, there
    needs to be a way of storing surplus power for future use when it’s dark, wind speeds are low etc. Huge battery banks could be used but some have suggested producing hydrogen gas by electrolysis which can then be burned

    At todays prices the pay back is only a few years.
    Also nice to see that you are feeding France,
    with their non-functional 'nucleaire'.

    I suspect the -ve values actually mean imports. We typically buy
    electricity from France




    We also export electricity to France at appropriate times. It's the
    strongest practical argument for not synchronising clocks with Europe,
    that one hour difference in peaks is very useful.

    AFAIK abolishing Greenwich time has never been seriously considered.
    (exept as DST)

    It has been suggested often, masked as remaining on BST all year round
    rather than put the clocks back in winter. Winter, of course, being the
    time when the hour's difference between us and France is most useful.

    Yes, I had forgotten about that.
    But then you still wouldn' be on French time the year round,
    because France has DST too.
    No doubt such a proposal would greatly annoy the Scots,
    who will then have their limited daylight hours
    at the wrong time of the day.

    It is possible of course,
    it is just what the Spaniards have been doing,
    ever since Franco. They seem to be happy with it.
    (but they are at much lower latitudes)

    As a matter of historical interest, the opposite has happened.
    Before WWII France had Greenwich time. The Germans changed it,
    and after the war France didn't change back.

    None of which tend to be built near power stations.

    My point was also that using electricity to generate heat when that electricity has been generated so inefficiently is stupid, if not

    French do it all the time. Perhaps they have realised that fuel for nuclear power stations is dirt cheap.

    That must be the reason for EDF being effectively bankrupt.

    The nonsense is all yours.
    Solar, what there is nowadays, doesn't need storage.
    Solar power generated tranlates directly into gas/oil/coal not burned.
    (at a competitive price)

    Unlike nuclear, those gas/oil/coal power plants -can- be regulated.

    Sounds like AppleScript (System Events?) has a regression in Ventura, or
    the way Ventura is presenting disks has changed. I get "NFS" for
    everything too.

    Try "mount | grep '/Volumes/<whatever>'". This will give you one line of
    output like this:

    /dev/disk5s1 on /Volumes/Foo (apfs, local, nodev, nosuid, journaled)

    Watch out in the grep if you've got disk names that are prefixes of
    other disk names. eg "Data" and "Data - Music".


    Or "diskutil '/Volumes/<whatever>'". This command will output something
    like this:

    /dev/disk5 (synthesized):
    #: TYPE NAME SIZE
    IDENTIFIER
    0: APFS Container Scheme - +2.0 TB disk5
    Physical Store disk4s2
    1: APFS Volume Foo 1.2 TB disk5s1

    The "(synthesized)" bit makes me wonder if more's going on in the murky
    bowels of the OS than we think, and perhaps NFS *is* involved.

    Anyway diskutil has more options than you can shake a (memory) stick at.
    The -plist option will make parsing very robust. Although, now you've
    got to parse XML. Swings and roundabouts!!

    I just got Ventura running on my 2013 iMac too, I just used the standard

    know how whether I got no SIP or partial SIP. I do have belt and braces security applied here (combo of using CloudFlare DNS in my router, Objective-See stuff, and a light Norton 360 installation).

    I also don’t use my iMac much anyway these days, and it spends a fair bit
    of time just switched off altogether.

    I suppose I had to weigh up the usefulness of having my iMac integrated properly into my iCloud ecosystem, and taking the chance of a rare security issue perhaps.

    To be honest, it is getting to the time where if I couldn’t run a contemporary OS to my iDevices, the iMac would be pretty much a brick
    anyway. Most of the stuff I use no longer works with it in it’s native
    state (things like the Photos library, my main requirement, but also Pages
    and Numbers docs are not backwards compatible to name a couple).

    or Numbers documents with Mojave (my last supported OS), from my iPad
    versions. And now I am trying the new Photos Shared Library on the
    iDevices, upgrading to Ventura had a similar status.

    It has always been my intention to eventually retire the iMac. But if I can squeeze a little more life out of it, all the better.

    As for performance, I still don’t think it’s degraded much at all, even from when it was new. Although the 512GB SSD I put in it a while back might
    be helping.

    I suspect most of the core OS hasn’t really changed a lot, it’s just the extra bolt-ons that might cause issues if the hardware is not capable of running them.

    Of course you can check SIP status in a terminal window.

    csrutil status

    Runnimg it here yields:

    System Integrity Protection status: unknown (Custom Configuration).

    Configuration:
    Apple Internal: disabled
    Kext Signing: disabled
    Filesystem Protections: disabled
    Debugging Restrictions: enabled
    DTrace Restrictions: enabled
    NVRAM Protections: enabled
    BaseSystem Verification: enabled

    This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state.

    Oh dear!

    A correctly configured Mac does not need such snake oil. Never.
    In addition you pay twice: At the cashier and with a much reduced system performance.

    This thread sounds like a reminiscent $Windows-thread$.

    I see the village idiot has hijacked and crossposted this topic now. He's sadly
    missed the point. The OCLP developers point out up-front that it reconfigures SLP to allow
    Ventura to run on some older hardware. Users therefore have the choice whether to upgrade or
    not in the full knowledge that there are potential security issues. Clearly my ageing
    machine is one which requires SIP degradation. Like you (AndyH) I'm fully aware of any potential
    consequences and may decide to re-install Monterey.

    Yeah, it was inevitable, I just choose to ignore and not reply anymore.

    I believe the same issue befalls Monterey too, but it can depend on the machine, from the text on their pages, it does seem that it can vary
    greatly what level of SIP you end up with.

    As you say, I went into this with my eyes open, knowing the risks and
    possible consequences. Same as installing the security softwares that I
    have. Maybe a vain attempt to restore some level of security again.
    Although I think the Objective-See stuff has the best chance of achieving
    that.

    FWIW, I expect there’s as much chance of my iMac being bricked by
    installing a hacked and unsupported OS as it has of being foobar’d by the security software I’ve added, that may, or may not, be effective anyway.

    My iMac is now at a point where if this all does go tits up, it really doesn’t matter, I’d just completely wipe it, and probably bung it on eBay for whatever it gets. I was almost at that point anyway before using OCLP.
    Of course I know it’s on borrowed time.
