Q: Safari keeps crashing/freezing after install of El Capitan

After the install of El Capitan, Safari 9.0 keeps locking up and or crashing.

I have a Mac Book Pro 15'' 2.3 GHz i7, 4GB Memory, 500 GB HD, iOS 10.11

 

When using Safari, I will have class work up and YouTube or iTunes playing. Before El Capitan it would do those processes with out a problem. Now it seems to lock up, unable to refresh, unable to exit Safari. I have to force quit and shutdown to try and get control back. Occasionally even after the shut down it will still lock up.

MacBook Pro (15-inch Mid 2012), OS X El Capitan (10.11)

    I'm not able to recreate the lag that you're seeing, @Alwayserik. I was even at 4K. He's good, but I am wondering how that channel is at over 6 mil. subscribers (even if half of those are real, it seems strangely high) and nearly 2 mil. on a 1 day old video...that's probably another issue.

     

    OK...back on topic...

     

    Are you sure it's not an Internet issue? Your ISP could be doing all kinds of odd things.

     

    @palegreenghosts - Good to hear your results. I haven't seen the very few nuances I had at first after the upgrade either. Maybe YouTube made some changes as well.  I agree on the hardware comment. I'm not ruling a hardware issue out of the equation. I do wonder if there's anything else that's not running at 100%, but is just off our radar.

    I also sometimes (very rarely) have slight lags when switching/closing code-heavy tabs with spinning beach ball, which goes away in couple secs, but no total freezes.

    I have since updated to safari 10.0 on el capitan and the problem is fixed. Youtube loads and plays fine in all scenarios regardless of what video it is. Seems they did some HTML5 fixes and improvements.

    Hopefully we can put this one to bed but I thought I'd chime in with experience from using Sierra (10.12) for a few days.

     

    • The tab closing/switching issue is still gone, hallelujah, and I've had no trouble yet from closing opening any tabs containing videos playing.
    • I've yet to have the same stuttering freeze that the last version of Safari gave me (I mentioned it in my last comment).
    • The Vimeo graphics glitch I've had the entire time appears to have also disappeared (occasionally vimeo HTML5 embeds would show a glitched graphic effect instead of their placeholder image until I scrolled away and returned).
    • It appears to have solved by issue of Safari frequently causing an isolated tab to freeze up and choke the CPU until I closed that tab.

     

    Unrelated to the above or this problem but it also fixed that horrible wifi disconnect problem I (and others) were having where the laptop would show a stable wifi connection and accessible internet but would drop traffic completely for about 30 seconds every 15 minutes or so (while no other connected devices did). I actually rushed updating to 10.12 in the hope it would address this as I didn't want to fork out for a new router which appeared to be the only other solution.

     

    I'm having very few programs refusing to run in 10.12. I had a lot more going from Yosemite to El Capitan.

     

    Lastly, a thanks again to any Apple engineers reading this who helped with this issue on the quiet. While it's frustrating that these (major) problems are not acknowledged, I'm glad there's still people reading these reports and ultimately issuing a fix.
