I suggest doing most of your online banking on your iPhone or iPad.I have a 2017 15" MacBook Pro. I use it as my primary computing device and outside of the crappy keyboard it's been working for me. I've had AppleCare+ on it since getting it in 2018. With Apple dropping MacOS support for previous MacBook Pro models, I feel like this model is next to be dropped come this WWDC. I know Apple typically provides security updates for older MacOS versions for 2 additional years but its an unwritten policy and could change. I hate how Apple isn't upfront about the minimum amount of years they'll provide security updates for their OS releases.
Last thing I want to do is be running insecure software on a computer I use for online banking and bill paying. I got plenty of devices so I don't feel like buying a new one, but I feel like I should go ahead and just upgrade. I don't really need the power that a 14/16" MacBook Pro offers, so a MacBook Air or 13" Pro would be fine. But I feel like the one I have is fine for my needs and would continue to work (outside of the horrible keyboard and the fact I have to get it replaced at least once every year with AppleCare when keys get stuck).
Not sure if anyone else feels this way.
Like, if you don’t feel secure doing that stuff on a desktop that hasn’t received security updates then an iPhone on the latest iOS or latest security update should be sufficient.
If your bank doesn’t have a dedicated app for your smartphone with many features and frequent updates then maybe I’d move my money before upgrading my computer.
I get that they’re maybe limitations and maybe your online banking services aren’t good on mobile. Idk. 🤷♂️
There many solutions to this issue. But you are definitely not forced to get a new MacBook, not until Apple has anctually announced the OS that makes your MacBook a legacy device.
