Problems with internet image upload /download on OS 10.11.6? Since about 24 Sept 2022?
I'm running OS 10.11.6 on a Mac Pro 4,1 (2009), because that's the most recent OS release that the computer can run.
Starting about 24 Sept this year, I've been experiencing a range of problems in several apps. The common element is that they all relate to image upload or download across the Net:
- In browsers (Safari version 11.1.2 (11605.3.8.1); Firefox 78.15.0esr (64-bit) – again, both the latest runnable releases), pages that serve frequently updated graphics (news sites, Google maps - even Google search because it's configured to offer image 'hits') do not load. They hang. Sometomes, after a wait, reloading the page fixes the problem. More often, it doesn't.
- I can no longer to upload photos on my desktop WhatsApp app (Version 2.2236.10) though, fwiw, I can still see and download images sent to me by others fine.
- Messages on iMessage that contain images are not sent.
- Images embedded in some emails do not download (Mac Mail 9.3–3124), even after hitting ‘load remote content’.
Now, I don't know web architecture or programming from an oak tree, but because (1) this all started happening at the same time, and (2) it's happening in several apps, I wonder whether some widely-used 'module' or whatever it's called in Internet architecture, something that deals with image file transfer, got updated on or around 24 September, and good old El Capitan 10.11.6 either 'didn't get the memo' or just can't be tweaked by Apple to deal with the new protocols.
Does anybody have any idea? I really would like to fix this...
Thanks,
