Mouse cursor retreats to bottom left corner of screen and doesn't want to leave it

For anyone who may be encountering this issue in 2021 or on an M1 device. None of the tips or tricks worked for me. Safe Mode, button combo start ups, updates, nothing. Skip it all if you're facing this issue.

What worked (so far, it's been 5 of days) with the help of a very knowledgable escalations agent at Apple Support, was a complete reinstall of the OS.

When doing that, he realised from Disk Utility, that the OS was never properly installed on the device (seemingly at factory), to begin with.

I backed up to an EXT HDD using Time Machine. Nuked the SSD (I wasn't a fan of this either but I had no choice because the disk was so borked that it kept telling me I needed more space to just reinstall the OS without nuking. It would tell me I needed 800 more MBS, I would delete 5GBs, It would then tell me I needed 1.27 more GBs. This repeated about 4 more times before we just decided to nuke it), reinstalled the OS fresh, then used my backup from the HDD on the migration tool during initial setup.

I've had no issues since doing that.

Hi Matti,

It should indeed still be in warranty, I purchased it just in April of this year. Though I purchased it in Spain and live in Ireland, so I'm not sure where that leaves me.

It hasn't been exposed to any high temperatures or anything (I treat it like my first born child). So could a battery issue be a manufacturing defect?

I still believe the issue is more likely to he SW though, given that the restart resolves for a period.

Thanks

I guess they would have had to rejig Logic for M1 anyways so it's definitely compatible. Again though, it can happen when simply browsing the web, but I think less so.

I'll grab the latest SWU but the notes don't mention a fix for this particular issue.

Well it took 2 days of average to heavy usage on Logic without the bug reoccurring. But now it has returned on day 3 post SWU, whilst only using Chrome to write an email. Logic hasn't been launched since yesterday, it was closed before midnight.

Chrome has 3 tabs open including this one and a Google doc I'm writing. CPU meter in my dock is showing just 1 bar at the bottom.

SWU completed and restarted. Will monitor the situation with normal usage.

This is now infuriating. I can't get anything done, and the one temporary fix available, to restart the device, is almost impossible to achieve because the mouse won't let you move there.

Spoke too soon.

Just happened again. A few full days of Logic had no effect, but it went during the first Facetime call I've taken since the reinstallation of the OS.
