M1 Mac Mini weirdness - help/suggestions sought...
Posted by: Cary
Date: August 03, 2022 01:20PM
I bought a new M1 Mac Mini ~6 months ago for my work computer.

At first, it was great. It continues to be good, mostly.

Running OS 12.1, 8/256 with a 1TB external SSD, using a case recommended here.

There are 2 issues vexing me:

1. Slows down to a crawl (intermittently) in Chrome and Firefox. I use different browsers for different tasks. Restarting the computer resolves this, for a while.

2. Intermittently, from sleep, I get a screen that looks like this:


Unplugging the HDMI cable and reinserting it clears it up.

I've tried: replacing cable with a "high speed" one and using the 2nd HDMI port on the display (HP 27f).

Should I be bringing this in to Apple? Any suggestions on how to resolve either issue?

TIA,

Cary

Try a UsbC to HDMI (or display port) cable. I've had similar troubles with the HDMI port on my mini

This. The symptom is usually a problem with the display sending the right signal back on wake-from sleep and swapping cables to use one that has a different adapter on one end (USB-C to HDMI vs HDMI to HDMI -- or USB-C to Displayport or USB-C to DVI, depending on what's available on your display) is the usual fix.

...

The slowdowns in Firefox are weird. (Par for the course in Chrome.)

Have you updated to the latest version of Firefox?

Have you run a malware scan?

Have you reviewed your Firefox add-ons and removed those that you don't need so much?

I have experienced no slowdowns on my M1 Mini, but I have experienced wake-from-sleep video display problem on occasion. Instead of the white noise screen as shown above, my display simply refuses to come out of sleep. And yes, I use a HDMI-to-HDMI connection.



It is what it is.

I have had all sorts of wake from sleep problems with an HDMI connection, even with video from a DVR. I think HDMI is just fussy because I've never had a single problem with a DisplayPort connection.

As far as your browser problems, does quitting and restarting just the browser fix the problem?
