Hello I'm still learning. I have created a smart group with systems that were compatible with Big Sur which I got this value
(MacBook(10|9|8)|MacBookAir(10|[6-9])|MacBookPro1[1-7]|Macmini[7-9]|MacPro[6-7]|iMacPro1),\\d|iMac(14,4|1[5-9],\\d|20,\\d)
I was wondering how I could get the opposite of it. Like create a smart group with systems that aren't compatible with Big Sur. I'm still new to this well at least with the regex stuff on finding the hardware. Thank you any help would be greatly appreciated.
