My bluetooth logitech mouse and keyboard get laggy when time machine runs. Sometimes I have to sit and wait for several minutes before I can effectively use them when a backup is running. Otherwise , when I move my mouse, it can take up to 30 seconds for the cursor to move.
When the time machine backup completes, my laptop is back to normal - lightning speed responsiveness.
This is unusual, I get no slowdown at all when TM is running, and use a similar spec MacBook. It sounds like an issue with the mouse and keyboard configuration. Have your tried with other mice or keyboards, or other ways to connect?
Yesterday I was even using a Windows 10 VM and it told me TM was running, and the mouse and keyboard were perfectly responsive (Magic Mouse/Keyboard).
I used TM scheduler for my server box and it worked fine.
Do we know where the BT receiver on the MBP? I use Logitech keyboard and mouse and I have both going to the usb receivers. I had a USB hub I used on my iMac and had both the receiver and TM drive off of the same hub. Same issue.
Through research I found that if the there is a high data transfer going on it can affect some wireless technologies. Moving my TM drive and USB hub to opposite sides of my iMacs USB row solved the problem
Digging this up, as this might be the cause of the Logitech issues I’ve been having as well! This is on a Mac Mini (both the 2018 MM and M1 MM)
I’d been googling for others that might have the issues, but I’ve found that my beloved Logitech K350 will drop and lag at certain points during the day. It didn’t seem to be at any specific time, but would react poorly to keyboard input. I didn’t have issues with the mouse, but that’s connected via Bluetooth. Before posting here asking for advice, I found this thread which could be the same issue I’m running in to!
I hadn’t considered that it might be Time Machine related (I’d narrowed it down to Mac related, as never had issues on Windows) and have instead ordered a Keychron keyboard. Depending on how my wrists get on with a standard keyboard (a cheap wired Dell had sufficed for a period without causing wrist issues), I might well try this again and see if it corresponds to Time Machine kicking in (and if it applies now I’ve a different time machine drive).
