I need to find a laser printer that works with Mac Big Sur operating system and prints a minumum of 60pages per minute anyone have a recommendation?

If the 60 ppm is a firm requirement you're going to have to pay some big bucks for one. For example: HP LaserJet Enterprise M608n claims 65 ppm and is about $1K.

I've had HP monochrome laser printers for a number of years now and have been extremely happy with them. What I look for are models for which you can get 3rd party toner cartridges. That's because for my model the HP cartridge is $80 per and I can get 3rd party cartridges for around $15-20 per.

The 60 ppm requirement puts you in an entirely different league of printers.

60 ppm automatically means laser printer. There are no inkjet printers that can move that quickly.

Only three such printers at HP. Will do both color and B&W.

If all you need is a printer (not a multi-function device), the VersaLink B600/B610 is reasonable at just under $900. Though it is black & white only. For those that do both color and B&W, they have these.

The Brother Workhorse Series tops out at 52 ppm.

You will need to choose a printer from your vendor shortlist that offers that level of printing performance, meets your other printer specifications, and fits your budget. Then, verify that the networked device is supported by Apple's built-in AirPrint, so you won't be concerned about vendor device abandonment.

I have been using a Brother laser printer for years and have never had a problem. It has worked fine with every operating system I've installed and with two Macs as well.
