My MacBook Pro M1 no longer sleeps after the update. same goes for iMac

My siteground email no longer connects afer update
Thanks for reporting Bruce. Have you tried to remove the account from the Mail app and re-add it.
A similar issues has been reported for the iOS 15.6.1 Mail app.
My macbook is so slow after update it is almost unusable
cmd+Space and type Activity Monitor. In the CPU tab the top resource eating processes are listed. What do you get? Send a screenshot if possible at contact[at]iphonetricks.org
my iMac started shutting down randomly and won’t turn back up unless I unplug it and re-plug it.
Thanks for sharing Dimitris. Is your Mac equipped with an M1 processor? Check for any recent software that you installed. If it’s not compatible with the M1 processor it might cause the unexpected shut downs. Simply, uninstall the software if you pinpoint it.
Does this help?
Thank you Patricia for replying so quickly. No my iMac is a 2017 model with Intel Core i7 chip. Everything was normal when it started doing it after the update. Could it be signs of a failing power unit as I read in some posts?
Not sure what to say. You might have to get it check by an Apple service shop… it’s strange though that it only started after the update.
Let us know if you have any breakthrough. Fingers crossed!
Hello – I’ve tried twice to install this update and it gets stuck at 25-30 minutes remaining.
mac mini late 2014
2.6 ghz dual core intel core i5
8 GB 16 MHz DDR3
(Yes, it’s old. So am I, for that matter.)
Thanks for reporting. What’s the current version on your machine? macOS 12.5?
Now the monitor connected via HDMI intermittedly shuts off then on again. And the USB-C monitor still goes black/no input after awhile.
It’s still broken.
Thanks for reporting Lyndon. Is this happening while you’re actively using your Mac?
Have you tried to check the monitor’s sleep settings? Check for Display -> Monitor Sleep and set to Never if available, instead of sleep after timeout or anything similar.
Also, are you using certified HDMI cables?
Some examples are:
– Premium High Speed HDMI cable – https://amzn.to/3RlEbsV
– Ultra High Speed HDMI cable – https://amzn.to/3RgZMCJ
After the update, when the screen goes to the time-out power down the computer shuts down and won’t start till then plug is pulled and plugged back in. 2019 intel motherboard. no recent new hardware or programs.
Have you tried to briefly press the Power button?
Also to fix try to Reset PRAM and VRAM:
– Shut down your computer and press the following combo after you power it back ON
cmd+alt+P+R. Hold the keys until the computer restarts itself. Release them when you hear the startup sound.Does it help?
