That’s a known issue for USB 1.1 device (usually for HID i.e. keyboard). The work around is to connect the device via a USB 3.0 hub.

Is that just an issue with the mac pro I’ve used this same usb device on a MacBook 2009 and Mac mini 2010 with no problems. Is it isolated to the mac pro both my mini and MacBook running opencore with Monterey to exhibit the same issue.
 
Can confirm just like others after third install Monterey now boot loops and unable to reinstall…created three separate installer flash drives on three different supported systems both creating installer apples way and then applying efi to the flash drives using open core and also straight through using opencore legacy patcher nothing works anymore. Reset NVRAM and SMC….Monterey no longer installs….Mac Pro 5,1

Same thing, MacBook Pro 10,1, OCLP 0.5.2, dGPU disabled (dead 650M), using HD4000 with NVDAResman and NVDAStartup kexts loaded to enable screen brightness control. Not sure, but GPU might be somehow relevant to this issue.

Safari 16.1 is almost unusable on YouTube. Disabling all extensions and clearing cache doesn't change anything. Disabling YouTube's "Ambient mode" (as I saw someone suggested) also doesn't help. Switching quality down to 360p helps a little, but CPU usage still stays high. And there are many sites that started to use too much CPU, it's not just YouTube.

Invisible Google results in the dropdown can be fixed with custom CSS:
CSS: 
body, input, button {
    font-family: "Arial Unicode MS", sans-serif !important;
}
The default Google's CSS uses Arial and sans-serif, and Arial is a problem. You can just remove it in CSS (in Safari Web Inspector) or change to any non-existent font name like Arial123, and search results instantly becomes visible. There is a /System/Library/Fonts/Supplemental/Arial.ttf file in Monterey 12.6.1 (and Arial font is listed in the Font Book app) but it looks like Safari can't use it properly. Another possible fix which doesn't require use of any extensions, might be:
Bash: 
ln -s /System/Library/Fonts/Supplemental/Arial.ttf /System/Library/Fonts/Arial.ttf
But I haven't tried it.

Reinstalling the patch fixed my slow typing issue in safari.

OCLP v0.5.2 Still running great.. Thanks to the Devs!

Any benefits to installing 0.5.2 (or 0.5.3) for 2010 Mac Pro models running Monterey? I'm still on 0.4.11 since most of the 0.5.x development was focused on Ventura.

Update: No issues upgrading to OCLP 0.5.3 and MacOS 12.6.2.

You will get all information needed by reading the change log / release notes published with each new OCLP version.

Definitely not: I have 2009-2011 systems running happily with Monterey latest (12.6.2) and Big Sur latest. Get a new disk or check your hardware on High Sierra to prove everything you own is still working.

Finally:

While this is primarly a Monterey thread and can find help here, there is a dedicated macOS 11 Big Sur on Unsupported Macs Thread

Agreed. I have Big Sur and Monterey on the same SSD, and High Sierra on my other internal SSD. All three work perfect. Had a reboot loop installing Big Sur, but that was my rush of things.

Updating to OCLP 0.5.3 didn't resolve the problem with Safari16.2 and the crashing of tabs or windows for me.

For Mac Pro 5,1, you may try my per-configured OpenCore package.

What GPU do you have? Nvidia ? Try OCLP 0.5.3 with RootPatch again.
