Wireless and Bluetooth Keyboard & Mouse Connectivity issues with Macbook on Mojave and M1 Mac Mini on Big Sur 11.4
My Bluetooth Logitech Pebble M350 mouse and Bluetooth Microsoft Designer Mouse have been experiencing intermittent loss of connectivity from my Intel MacBook on Mojave 10.14 for past 1.5 years. It was working fine on High Sierra until I upgraded it to Mojave. It was completed unusable. I had spent many sleepless nights getting back to the point of getting the mouse to work again - purchased a Samsung external SSD hard disk to backup all my stuff; reinstalling my Macbook via internet restore to High Sierra again; upgraded to Mojave again. After a few days, the Bluetooth Microsoft Designer mouse turned laggy and using it was extremely disruptive as it lost connectivity every less than one minute. I went through the steps of resetting SMC, memory, removing the bluetooth profile in one of those pref config file, resetting bluetooth setting, etc. All didn't work. I then purchased a bluetooth Logitech Pebble M350 mouse and the problem was gone for a few days. The same old issue came back to haunt me again until today - 4 July 2021.
Last month I purchased a M1 Mac Mini and my unified Logitech 920-006314 MK270R Wireless Keyboard and M185 Mouse have also been experiencing intermittent loss of connectivity from my M1 Mac Mini on MacOS Big Sur 11.4. The responsiveness was worse than that on my macbook. The keyboard was completely near unresponsive or dead. The mouse was down to 20% responsiveness. I had to keep dragging the mouse to find a laggy mouse trail or motionless mouse arrow.
Both my iPad after upgrading from IOS to iPadOS, they cannot be turned on until I leave them on the charger for at least 3 days even though their batteries are on 100%.
For the above wireless issue affecting my M1 Mac Mini, the temporarily workaround has been that of using a Type-C USB hub and connecting the unified keyboard/mouse wireless dongle to a non-USB3 port on the Type-C USB hub albeit there is still mild lag to the keyboard.
I am rather disappointed with the Quality Control of OSX for the past few years. I would rather OSX slow down in refreshing its OS. What is the hurry when everything is stable, reliable and secured?
I hope Apple is aware of this vast reported wireless/bluetooth problem affecting many users and I also hope I am NOT the only one having the 'unbootable' ipad issues.
Apple should address all these and not remain quiet about it. It should at least put this up on the Apple Website to create awareness of the prevailing problem before it release a firmware update if available.
