Even if you’re a casual user (i.e. not a tech geek) you should download this app. You will find it immensely helpful (especially in times of need like repairs, resale, getting replacement parts, etc.) for identifying your exact computer or idevice. For the Apple/Mac afficiando or collector, it is an invaluable tool. It’s also fun to just take a trip down memory lane through all the many, many years of Apple products. How many products have you owned? Do you remember your first Apple II from back in the 70’s? Ian Page has done an excellent job with this app. Thank you Ian!
