Looking again for a used Mac to help a client. Doesn't need to be too recent, only needs to able to run Big Sur so I think anything 2014 running Yosemite and later would be fine. It won't be worth it for me to buy a new one or even spend a lot on a used one but willing to pay a reasonable amount for a working device. If it can run Monterey (i.e. 2015 or newer) so much the better as the software I need to run on it is likely to update it's minimum requirements at some point but I'm sure it will be some time before that happens. Thanks! Gary
