Question: Safari 13.1 is Buggy ... and another thing...
Perfectly legit sites like Chase.com error with "Problem with this webpage" on some machines. Other machines with same OS (10.13.6) and same safari version (13.1) work fine.
Apple really needs to stop being so "dear valued customer" Microsofty about things and get back to making solid products running solid software. At some point soon my users' frustrations with these problems are going to outweigh their desire to not (re)learn other OSes. And no, upgrading everyone to Catalina is NOT a solution because Apple does not exist in a vacuum and our OS and business-critical software needs to work so updates have to be coordinated.
Thanks,
Jeff
