Never had a problem with pictures, and I send a ton of them; it’s a standard format. Are they using jpegs? If it’s tifs, she can set her default to Windows and it will work on both platforms. Or perhaps it’s her camera format.
If she is sending a screenshot that’s a png file unless converted, dunno if that’s the problem.
Office works fine on Mac, so does the full range of Adobe apps. Of course email, browsers..
Obviously if you have an app you must run and it only runs on Windows, you have to have a Windows box - or you can buy a Mac and run both Windows and MacOS.
There are some apps that require Windows, but outside of specialized business apps and small highly specialized apps, these are pretty rare.
If you’re a heavy duty computer gamer, you should be in a PC.
I was talking about forwarded pictures in emails. She can see them when she gets them, but when she forwards them, I can’t see them.... I can’t tell what type they are.....only see the message ‘Type is not available’. This happens 8 out 10 emails she forwards to me.
