Spenser has an old white MacBook that he uses to tether to his Nikon cameras and take pictures of his astronomy. There's a solar eclipse coming in 2024, and he wants to know if he can use it even though it's over 10 years old now. Leo says it may be better to see if there's a new version of the software used on a newer Mac. Unfortunately, the old version of the software won't work on modern macs because Apple stopped supporting 32-bit applications. So you'd need a newer version of the software. A good option is to get a certified refurbished Mac from Apple directly. The least expensive Mac is the Mac Mini, but Spenser will be out in the field, so a laptop would be a more practical option. The least expensive would be the MacBook Air. And with everyone selling their old Macs to buy an M1 Mac, the time is good to buy one, even on eBay. Just make sure you can trust the seller.
