Did Indigo make a change to how sleep is handled with V7?

I am not sure exactly when this started, but my Indigo suddenly started going to sleep when the computer is not used for periods of time. The issue comes up when I try to access with Indigo Touch on iPhone and all devices are reddened out and have no access because the PowerLinc 2413U is offline. This problem is fixed by connecting to the computer running server, either at the computer itself or with Screen Sharing. But it has happened multiple times now, after no problems for many years. I am running with Start and Connect to Indigo Server on this Computer. See screenshot attached.

Any ideas of what may be happening or how to fix?

Have you recently updated the operating system on the mac running Indigo? Apple seems to reset those settings every time.

I set my server to never sleep. And I have to redo it with each major update.

This is becoming a more frequent issue with macOS - despite the settings, the Mac will still often notify applications that it's going to sleep. You can try resetting the PRAM and then setting it not to sleep again.

Thanks. I will try PRAM reset as the setting are correct yet Mac keeps sleeping. In case I fail, is there a way to wake the Mac from Indigo Touch? Right now the only way I can wake the Mac and get Indigo working is with a laptop or other PC to VNC - would be easiest if done from Indigo Touch, or even some other iPhone app (I can try VNC for iPhone I suppose, but type is so small).

Re: Did Indigo make a change to how sleep is handled with V7

I've somehow also lost control of the sleep issue on one of my two Indigo setups. I can stop sleep on my Mac mini, but no longer on the MacBook Air [that frustratingly is remotely located so I only have a chance to fix this once every couple of weeks - also makes it hard to diagnose and correct]. Obviously the MacBook has added complexity of battery state and lid-closure events to suppress.

I've tried one of the prevent-sleep apps, as well as the command line approach, but something must be screwing this up.

Given sleep management is such a fundamental issue for Indigo's successful operation, I wonder how easy it would be to incorporate managing (and therefore correcting) from a plugin (or at least a script that periodically runs?).

Adding to my woes, Back to my Mac has become completely unreliable over the internet.... aaagh.

Anyone else suffering this issue?

Re: Did Indigo make a change to how sleep is handled with V7

I don't think there's much more that we can do beyond disabling app nap which we did back in I6 (and it remains for I7). Apple seems very determined to put Macs to sleep, regardless of what users actually want. It's particularly bad on MacBooks, though I admit mine doesn't have an issue staying awake.

BTW, have you tried zapping the PRAM?

Re: Did Indigo make a change to how sleep is handled with V7

no I haven't tried resetting PRAM yet, will definitely try that next visit.

still curious if anyone uses a script to automatically check the mac's sleep management parameters on indigo startup (or more frequently), and notify or correct if necessary.

Re: Did Indigo make a change to how sleep is handled with V7

I started having this issue when I bought a newer Mac Mini last year. I installed Amphetamine (follow Jay's link) and that solved the problem completely.

Re: Did Indigo make a change to how sleep is handled with V7

Just for the benefit of anyone else attempting to use Indigo on a MacBook, it isn't possible to suppress sleep unless you meet Apple's strict requirements for 'clamshell mode'. Apologies if this is discussed elsewhere (I can't find on this forum). That means, you must have attached a screen, keyboard, and mouse. 'Blank plug' screen emulators are available that may bypass the need for a screen, and wireless keyboard/mouse are technically ok (if they stay charged!).

In spite of this I personally still found clamshell mode prone to break in my setup and hence not suitable for Indigo running at a remote location. In exasperation I've upgraded to a Mac Mini. Its annoying (a) because older MacBooks are super cheap and otherwise perfect for Indigo (b) have built in UPS; and (c) they are easy to mount (when closed!) in an enclosure/cupboard...but having the screen etc integrated is super handy compared with having to connect a screen to a Mini at an awkward location.

The references to anti-sleep apps such as Amphetamine appear to be a red herring (for MacBooks with the lid closed). Amphetamine's website (corroborated on the Apple support site) provides detailed explanations of clamshell mode and how it can't be subverted by an approved app. https://amphetamine.freshdesk.com/support/solutions/articles/43000068869-amphetamine-does-not-keep-my-mac-awake

Amphetamine does call out a non-approved kernel extension as a potentially viable workaround, but presumably that carries significant risks - any tried this approach?

Re: Did Indigo make a change to how sleep is handled with V7

Would be nice... though I'd have though there would need to be an effective configuration/profile to enforce...(??) Disabling sleep is still an available setting in a MacBook's config, however the setting has no effect once the lid is closed.
