MacOS 12.2 battery drain and hard drive spooling during sleep

Jerry C

This is not a Capture One problem, but may affect external hard drives on desktops as well as causing shut down of laptops. Either could lead to data loss. Here is the problem and a temporary fix until fixed by Apple.

There are numerous reports of Mac laptops draining the battery due to repeated Bluetooth activation during sleep.This bug affects desktops, as well, although there is no battery issue. After updating my iMac Pro to MacOS 12.2, unless I turn off bluetooth or disconnect all bluetooth devices, when the iMac Pro sleeps, the external disk drives spool up and then go back to sleep at least once a minute. This is not good for the drives. Turning off bluetooth and using a wired mouse and keyboard gets around the problem.

Alternatively, you can set Energy Save to prevent the Mac from sleeping, although this will not address the battery problems on laptops. Many external hard drives will spool down after a period of idling.

    Jerry C Wow thanks for sharing this info.  I have wondered about batterY drain on Macbooks and this could be part of the issue.

    Out of curiosity what verions of macOS Monterey have you been able to run Capture One 21 successfully on. Have you managed to install any other version other than macOS 12.2 i.e. 12.3.x or above?

    This problem was corrected and I do not see it with Ventura. I am able to use Mac OS Ventura 13.2.1 with Capture One 22 and 23.

    I was able to use the last version of Capture One 21 (14.4.1.16) with the both the last version of Monterey and with Ventura 13.0. I then upgraded to Capture One 22 and later 23. I have not had problems that I can relate to and combination of Mac OS Ventura and any version of Capture One 22 or 23.

    Jerry C Yes, I also did some digging after seeing your previous comment and found that it was fixed in subsequent macOS firmware; seems like these sort of issues are taken very serious by Apple.

    It's reassuring to hear more person say that the latest versions of Capture One 21 worked with Monterey 😊 

    ... and it's a bonus to hear that it also worked with Ventura 13.0 prior to you upgrading to Capture On 22 and later 23. I think I personally will postpone the Ventura upgrade for when I update my Capture One software and focus on getting Monterey first to make sure none of my other apps break.

    Again thank you for your feedback, much appreciated 😊

    Warm regards
