We got a few new M1 Mini's at our shop. Only downside so far has been the XMF client, and if you use it their Measure App for the colorpathsync calibration web software doesn't work on 11.0+ at all, intel or m1.
I have a PC next to me to run XMF for the time being and Fuji let me know we're the first shop to adopt the new m1 Macs. they're working on an update for XMF that should be out sometime early spring that will work on the 11.0+ MacOS.
We got the cheap m1' minis (8gb ram model) and I kid you not, it runs everything faster (InDesign, Illustrator, photoshop, acrobat with Pitstop) by a lot, over our 2017 iMac 27" with the 4.2 GHz Quad-Core Intel Core i7 and 32 GB 2400 MHz DDR4 ram.
Until the XMF update, I'll be using the PC next to me like I said which sort of sucks, but hey. My old Mac is going to update our proofer/plater's station and move our FTP server to it (current FTP server is an older iMac running 10.4) when it bites the dust.
