Users complain of video, wake, login freezes in Lion

updated 12:55 pm EDT, Thu July 28, 2011

Video issues linked to QuickTime?

Glitches in OS X Lion are causing freezing for a number of users, according to complaints. The problems are moreover happening under a variety of conditions. For some people, freezes are triggered on waking from sleep. 2011 iMacs appear to be the worst affected in this regard, but some MacBook Pros are suffering the same trouble. Only a reboot temporarily solves the situation.

Some other people are experiencing freezing at Lion's login screen. Disabling automatic graphics switching has been proposed as a solution, but this may not necessarily help. Still others are dealing with occasional freezes when trying to play video, regardless of the app. QuickTime, iMovie, iPhoto, iTunes and GarageBand are all potentially subject, as is a web browser trying to play YouTube videos.

The breadth of the video and graphics issues may mean they are connected to some underlying components in Lion, such as QuickTime. There might also -- or alternately -- be flaws with the current drivers and firmware for graphics chipsets. In either scenario Apple is likely to release updates as soon as it can test fixes to the most critical bugs.

    Strange.

    I installed Lion on three Macs (two laptops, one iMac) and no-one has had any of these issues with them. Loving the new update. :)

    1st interation Apple products

    People should learn by now NOT to buy / upgrade to a new generation Apple product until the bugs are ironed out. I will consider upgrading to Lion in 6 months.

    macs suffering since 10.4...

    ...the latest firmware 1.0 MBP update caused my external iMac via displayport to lose brightness (full on) in external monitor mode, my sata3 ssd is stuttering & non-booting sometimes, the dual link displayport adapters I tried for 2 years to get to work with my favored 30" matt cinema never lost some kind of graphics distortion...

    The last professional macbook-large display rig that worked well for me was a core-duo/30" running 10.4.11 although with 2G of RAM it was very limited for pro use ?

    Apple profits may be roaring from iOS & Lion, and the hardware industrial design is an absolute favourite, however I am starting to have my doubts about the ability of Apple engineers to offer a fundamentally functional pro-portable system....

    Dual-link display woes are still commonly listed: http://store.apple.com/us/product/MB571Z/A?fnode=MTY1NDA5OQ&mco=MTA4MzU1ODY

    Should Apple be focussed on getting existing hardware working before offering new products that only seem to spread thinner the resources clearly needed to fix fundamental functional problems, like snow or loss of brightness control on their flagship professional systems ? ? ?

    Battery Life

    I haven't experienced freezes on my early 2010 17" MacBookPro, but I do feel that I'm getting much shorter battery life with Lion installed....

    youtube freezes

    i've had my 2011 i7 imac freeze twice already when trying to start a video from youtube. not sure if it was a coincidence but i'm not too broken up about it since i expected some bugs when upgrading to a brand new OS.

    Safari/Webkit browsers

    Safari and Chrome seem to have problems with images parked on iDisk. They download instead of displaying. If you copy their URL then paste, they download. Paste the first part of the URL, then type in the file name, it seems to work fine.

    Firefox doesn't have this problem, and images from other hosting sites don't act up, so I guess it has to do with Webkit.

    Video freezes

    I've been getting freezes (about eight of them so far) since upgrading and all have been related to online video. They have all been through different services: youtube, viddler, vimeo, and others. Half the time I get the beach ball of death that never goes away or I get nothing, just the cursor stops doing anything. Either way the only fix is the hold down the power button for a hard restart. (no keyboard shortcuts work for restarts or forcequits either).

    It's to the point where I'm afraid to watch any embedded videos online anymore.
    (I use a '11 iMac btw, just a month old)

    Cleared caches?

    I had some very significant problems after updating to Lion. Since OS X problems are generally caused by corrupt preferences and caches - and increasingly just caches - I did a Safe Boot to clear the caches. Then restart.
