Safari can't log into Apple websites (discussion forums, developer forums, itunes connect) High Sierra

For a while now from Safari I have not been able to log into Apple websites that require a login. These forums for example, or iTunes Connect, or developer.apple.com. It says that Safari cannot open the page because it can't establish a secure connection to the server "idmsa.apple.com".


I've spent three hours on the phone with Apple Support over this. Ran through every suggestion in their books, even reinstalled the OS. Nothing fixes it. They basically said the only solution was to update the OS to Mojave. Which might not fix it, but it might.


So really, High Sierra doesn't work with Apple's own sites? That cannot be true. There would be some mention of it online, I would think? I can't upgrade to Catalina. I might do Mojave, but at this point I just want to leave this computer running High Sierra to maintain the highest software compatibility. I plan to get a new computer soon, so this one is a legacy computer.


I can use Firefox to access this developer forum and the other sites, but I find it super ironic that Apple themselves cannot help me to access their own sites from their own computer using their own OS which is only 3 years old.


Anyone have any suggestions on how to fix this problem without updating the OS?

Anyone have High Sierra and able to access these forums, iTunes Connect, or developer.apple.com?


Thanks!

Your post is the first post I have seen where there is a problem in Mojave. In the Mojave computer/partition, are you running any anti - virus programs? Using a VPN?


Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor.

You might try running the Mojave 10.14.6 Combo Update:

Download macOS Mojave 10.14.6 Combo Update

The Combo Update is a fuller install, as opposed to an incremental "delta" update, so it should overwrite any files that are damaged or missing. (Or hopefully updated) It does not matter if you have applied it before. It should preserve all your data and settings but that said you should always have a backup.

It may not help, but try/running posting the Etrecheck report while booted into your normal user account. If the log won’t post, try posting it in Pastebin and provide a link in a reply. After pasting the report in a PasteBin page, go to the top of

the page, and copy the address in the URL bar. Paste that in a new
