Mac Studio bluetooth very slow to load at startup. Is this normal?

Same with my M1 Max Mac Studio. I tried turning off/on BT and using a different mouse but the same problem persist. The same mouse would work fine on my 2014 Intel iMac. I do note that the M1 Mac Mini and M1 24 inch iMac in my house both have a ~ 3 second lag upon initial connection. I note similar issue with the Mac mini and 24 inch iMac at the local Apple Store. So, M1 Macs do have a delay in BT connection.

Back to my M1 Max Mac Studio. I reinstalled the OS but the same problem persist. I do note that if you click the mouse, the mouse would then connect in about 3-4 seconds. It seems the computer is waiting for a BT signal before it wakes up. I worked with Apple's senior advisors several times over the phone but they can't fix it either and send the info to the engineers higher up. By that point, I was fed up with it and returned the Mac Studio to the local Apple Store.

I bought another M1 Max Mac Studio just now, hoping that it was an isolated issue. Guess what!! Same problem! Without stimulating the computer with a click, the connection lag can be over one minute!! That's when I realized that I better do a different search online to see if others share the same issue. It seems this is inherent with Mac Studio.

As Mercury88 told previously, Turning off FileVault will solve your problem !

I did it, restarted my computer and it's starting very fast, with no Bluetooth delay.

otherwise, you may just keep the keyboard linked physically to the mac. But the mouse will still need 30sec to 1 mn to connect..

As of 6/5/22, I updated my Mac Studio to Monterey v12.4 and now the Apple BT keyboard and Magic Mouse are connected as soon as I'm offered the input box for my password to log into the computer! :) On a side note I cycled the File Vault before updating, but it didn't fix it for me like a couple others, but could be that the combination of that and the update to 12.4 were vital. Anyway, this is the Mac experience I've known since switching back in 1997. I used to work for Apple service in the mid 2000's as well, so I am well informed. Even so, sometimes it's beyond your control, till it isn't. lol Cheers!

Turning off FileVault will solve your problem.

Hi Mercury_88 ! I did it ! I turned the fileVault Off "et voilà" the mac studio springs and connect mouse and keyboard in matter of seconds.

You have found how to fix the BT Issue ! Thanks a lot !

It has been reported that this is caused by using FileVault. If you turn that off then no delay.

*** Hi All. I have some interesting findings as of today. ***

I do not believe this is hardware related / specific to the Mac Studio. I have a 2020 27" i9 iMac for my work and was recently required to bring it up to date for network security reasons. I was running Big Sur up till this point and had no issues with late mouse pairing over BT. After updating to Monterey 12.3.1, I now have the same issue with it as I do my Mac Studio. It's taking close to or over a minute to connect the mouse. So, while this isn't great, it certainly is better than a hardware or firmware issue and once Apple decides to address it, should be a much more simple / quick fix.

For me it was interference from my usb 3.0 hub. It was resting on top of my Mac mini and I just moved it about 2 ft away and problem solved.

1. Keep the keyboard cable attached to Mac (that will eliminate that delay)
2. Use the return key to highlight your name and then you can type in the PW without having to wait for mouse to pare.

Just leave the keyboard cable plugged in all the time if you have an open port

Same here. Running Monterey 12.3.1 on a brand new M1 Mac mini. Needs about 30 seconds during boot before it recognises bluetooth keyboard and mouse. Started with my 3rd party combo first but then tried a brand new Apple KB and Mouse which had the same problem.

Same here randomly. Sometimes it is fine. Sometimes it affects mouse, keyboard or both. Sometimes the mouse is recognized after clicking and waiting a little. Sometimes this don't fix the problem. If the problem is with keyboard, it is not usual to get fixed pressing keys. If I power off and on mouse and/or keyboard, then they are recognized instantly

For me, I use Macs since 2010, this is a thing that I have always had, and I consider this normal. On my MacBook, multiple iMacs, and a Mac mini that I have used over this years, I always had this.

So I don't consider this to be a Mac studio issue

How often do you really "start up" the Mac? I just put mine to sleep.. It wakers very fast with either Magic mouse or KB.

It wakes so much fast than my 2013 MP.

Same here. Chatted to Support about it. They tried a load of things but to no avail. I reckon we'll have to keep the lightning cable handy for plugging the keyboard in and wait for them to fix it
