Hi,
I have the M1 Mac mini and the M1 MacBook Air (both base models) - I also have the 2018 i7 Mac mini with 32 GB RAM and eGPU (RX 580) and a 2016 MacBook and a 2019 15" MacBook Pro (base model, but with 16 GB of RAM).
The M1 MBA seems to be fine, have not had too much time to use it the past week since I got it but it convinced me to also get the M1 Mac mini. I normally browse that WWW and use Plex and my heaviest task is editing 4K H.264 footage in FCP (with some MotionVFX and other plugins). For that the M1 MBA was quite fast, thus the decision to get the M1 Mac mini for home.
But while the M1 Mac mini does perform well in FCP (at the beginning), after some time, the Mac becomes laggy, opening or switching apps seems to take a while (up to 10/15 seconds), then the in-app performance is lacking too, Safari at the moment had problems recognising my keys while pressing them or it takes a second or three to open a new tab an register the letters I have already pressed.
Clicking in the menu bar to take a closer look at some items sometimes takes another second or two.
As far as I have gathered, it might be related to uptime, as the Mac is quite responsive with every task the first hour or two.
At first I thought it was related to USB, Thunderbolt and Bluetooth, as I have the OWC 14-port TB3 Dock connected (now not anymore, it has to be replugged after a restart) and an MX Master 3 (for Mac, hahaha) via Bluetooth (now via Unify Dongle) and an USB 3 device.
Now I just have connected the display to the innermost USB-A port and connect from the Dell's four USB 3 ports (one Unify Dongle, one SSD and whatever comes next).
During initial setup I also had the problem of not being able to connect the MX Master 3 (it would have been its first computer, just bought it) or the Magic Keyboard with Numpad (A1843, worked fine on the 2018 i7 Mac mini).
Then I had the idea to connect my old Apple keyboard with USB cable (which works fine on the 2018 Mac mini and a Windows 10 box - its main use) and a USB mouse.
The mouse was registered if connected directly to the M1 Mac mini, but not via the USB keyboard, which also did not get recognised. A "logickeyboard" for FCP X helped me out in the end.
I still cannot get the M1 Mac mini to recognise the Apple USB keyboard though.
I also did a clean install at some point (this sentence took five seconds to appear after I typed "I als"), which is a bit more cumbersome, but doable using this
Apple Support KB. (looking up the link in the Safari browser history took almost a minute with all the lag, but I will restart once this is posted)
The clean install did not help. I am on the verge of returning the M1 Mac mini or getting it replaced (however long it takes nowadays), as the performance in FCP is WOW and 4K playback is buttery smooth, but the overall performance is merde.
PS: The CPU was hardly above 30% (using iStat Menus), though the RAM usage is often around 75% (pressure around 70% - mostly yellow).
Well, anyone any ideas?
