Well, shit.
Yes, a Mac would solve the problem. But you’re correct, they are priced ridiculously. I would love to own one. In fact, that’s why I have my Kofi (buy me a coffee!) page set up and my Patreon account, in the hope someone(s) will love my work enough one day to support it to the point I can afford one.
I would be thrilled with a desktop version. I had an iMac years ago I was in love with. Alas, some drug induced asshat broke into my house and stole it. I was livid.
I will research further and see if I can figure out what’s going on with your photos. I’m techie enough to be intrigued and want to help!
