Mountain Lion Frustrations?!

[chrisherbert]

Airplay. Why the hell is there a 1-2 second audio delay. And the audio cuts out too for a second here and there. I have the latest mid-2012 13" Macbook Pro, and the latest AppleTV. So annoying.

The issue is the quality of your network, not the speed of your Mac. If possible, have at least one of the devices (Mac or Apple TV) plugged into ethernet rather than wifi.

Unfortunately most people's wireless networks aren't in great shape, and airplay is probably the most demanding application imaginable for wifi. Unlike prerecorded video, they obviously can't use buffering to mask problems.

Well make sure you have a good backup. Installation of ML here (on rMBP, so using current Lion) just trashed the machine completely, "there was an error installing OSX". Recovery utilities couldn't repair the disk, reformat and start again job. Bagh...

Here too. Seems like it's shooting badly into the partition. The disk is 100% fine.

personally, i cant get iMessages on my phone to work with Messages app. I have seen a lot of other people have this issue. If you are using one apple id for your itunes and a @me.com address for your iCloud, it seems to be causing a lot of the issues.

The only way I can get my stuff to sync is to have the person I am messaging enter my icloud account email address in my contact in their iPhone, erase all current conversations we are having on all devices involved, and then initiate a new conversation from the Message app on my mac and bam every thing is on all devices. This is the only way it will work. I have spent hours on the phone wil Apple Care and they couldnt figure this out and how to actually get it to work properly, like advertised. Obviously, this crap isnt ready and it doesnt "just work". Really disappointed.

If I send a message from my phone first with a NEW conversation, it comes from my phone number. The conversation DOES NOT SYNC with the MAC!

I even tried to do this and then continue the conversation on the MAC and it wouldn't even send the message!

Now if I send a message first on a NEW conversation via my MAC it WILL show up on the phone with the settings described above and sync to BOTH devices. Works great. Problem is it's VIA MY EMAIL! Many people do not want this to happen!!!

It took me a few different tries to figure it out, but here is what I did and all my accounts and devices (2 iCloud email accounts and 1 phone number between iPad, iPhone, and iMac) syncing messages perfectly.

With all devices on, I used my iPhone to re enter and re log-in each iCloud account in settings > messages. With each entry, I got a confirmation window on my iPhone telling me that the changes are taking place on my iPad and on my iMac. All devices are receiving and sending messages to each other and from others, using both email accounts and my phone number.

Hope this helps you, and by the way, I am also using iOS 6 on my iPhone and iPad. That may have something to do with functionality as well.

My biggest issue is daily lockups due to what I have come to believe is a GPU hardware acceleration issue. At first flash causing the problems, but it happens with quicktime and Click2Flash as well. Which leads me to hardware acceleration.

Otherwise I'm fairly impressed.

So far I like it however I wish they would have left the time as a display for the battery on the Macbook Pro. You can only have percentage now which is useless to me. I know I can click on the battery to see it, but why can't I just normally display it?

I've had none of the problems mentioned with regards to sluggish Mission Control and Safari. Mid 2012 MacBook Pro here.

 

[quasinormal]

I'm frustrated in general because I'm stuck on a 3G connection for which I pay about $15 a gig, so no Mountain Lion, no movie store rentals- just lousy browsing or the odd book.

 

[Michaelgtrusa]

For the second tome after awaking from sleep, mission control dose not work! Nor can I move from space to space I have to restart!

 

[Elven]

i7 2011 iMac, and no problems with upgrade from Lion, running smooth as silk and quite happy with it, installation was prolonged I felt but this is the first iteration of ML.

 

[Apple...]

Guess I'll wait until an update comes out to fix some of these problems. Thanks for posting everyone!

 

[Predator69]

Some basic functions like the battery meter now showing the time left by default anymore .

This bugged me as soon as ML booted up

Zero issues here with a clean install. No choppiness, lag, and my wake up time is way faster than with lion.

Notification works fine, except iMessage isn't fully integrated yet with iOS.

Happy camper here. Was expecting issues as I have read, but must have been one of the lucky ones...which is rare.

 

[bushido]

i have a mid2009 mbp upgraded with an ssd and 8gb ram and ML is FLAWLESS, its so fast and quick and no problems at all. in fact my mac seems to run smoother than my sisters new vaio even though my mac is 4 years old

Downside

The only downside is a certain Japanese musical instrument hardware manufacturer whose name rhymes with "Poland" who don't have drivers for a number of their hardware products despite developer releases of Mountain Lion being available to perform tests for some time.

So, I might have to wait 3-6 months for drivers for equipment I use regularly.

Luckily, I have a Lion install on a Firewire 800 drive just for these occasions where audio drivers haven't been written for things and I do have a workaround if I don't want to reboot (another audio interface that does appear to have drivers).

The other thing that is a bit unusual: I have a powered USB hub that doesn't appear to be detected by mountain lion and none of the USB devices are detected either although another exact duplicate of this device is being detected. Might be a problem with the usb hub.

Mission Control is choppy as HELL when Safari is open. If I hide it with Cmd+H it'll be smooth as butter. Then when I unhide it, super lag-a-muffin. Like the desktop background is all the way back before the windows even move sometimes. I'm on a Retina MBP, Lion didn't do this.

I'm here now checking if there's a thread about it.

I don't know why ur experiencing lag it is fine for me.

I have installed ML on a base model 13" Early-2011 MBP and it's really smooth. Upgraded from Lion but considering doing a clean install.

 

[sine-nomine]

Mountain Lion took a long time to install. I had negative time remaining at one point with the progress bar full, then it jumped back to being half full and showed I had 19 minutes left...for about half an hour. Total install time was nearly three hours. Of course now that it's all installed, it doesn't matter, but I was worried for awhile.

Safari 6 slows to an absolute, constantly-beachballing crawl if I have around 20 tabs open. Responding to a right click in a web page, or responding to a Command-W or x-ing out a tab may take as long as 10 minutes. Not even close to kidding. I pressed the 'x' on a tab, got up, washed a few dishes, made some tea, sat back down, had a few sips, and then finally the tab closed. During this time (and when this happens in general), the cursor became a beachball when moved into web content, and while I could switch tabs, I couldn't interact with any page in any tab in any way. Right-clicking the Safari icon in the Dock didn't give me the option to Force Quit, so ML must have thought everything was just fine. Command-Q does quit Safari immediately when it behaves this way.

Also have problems with Safari using massive amounts of CPU somewhat randomly. With a few tabs open with pages from this forum, CPU utilization will sometimes suddenly shoot up to 160-200% and sit there until I close most tabs. Any presence of Flash on a page whatsoever will immediately bury the CPU at 200% and keep it there, rendering the whole machine sluggish and murderously hot. Safari 6 under Lion didn't seem to do this, though I only used it for a few hours, so who knows.

Two-finger swipe from the right edge to bring out Notifications frequently doesn't register. I have to be super careful. It's really not that troublesome, but I hope Apple tweaks it a little in future point releases.

So other than one very temporary annoyance during installation and a mildly annoying gesture issue, the only real problem is Safari 6. Overall, though, ML runs ever so much better than Lion. With Lion, I routinely had strange glitches and various issues that really grated. There wasn't a time when I used my machine that I didn't wish I was back on Snow Leopard (whose install disc I wasn't able to find or I'd have gone back fast). So far with ML, I'm really, really pleased. I haven't once had the urge to dive into my storage shed to locate my Snow Leopard disc. I'd call that an improvement.

people need to install with CAUTION

I'm having many problems with ML personally:
https://forums.macrumors.com/threads/1413572/

I normally wait until I updated to a new OS. This time I updated ASAP b/c i hated lion but look ML crashed my whole system!

so people please install with caution. read these threads--you'll see the truth-- many people are having different issues/buggy problems. IMHO, this is the vista and the beta not a final polished release. I am not a developer/ I am a consumer, I don't like reporting bugs like I am a developer.

 

[OllyW]

Mountain Lion is running smoothly on my iMac so no complaints there.

What's bugging me is the Snooze duration for notification alerts. In previous versions of OS X alarms & reminders had the option to repeat it in 1 minute, 5 minutes, 15 minutes, 1 hour, 2 hours, a day or a week but now all you get is a pretty useless 10 minute or so Snooze.

Is there an obvious (or not so obvious) setting somewhere to give different Snooze options?

 

[teamrusnac]

iOS6 is supposed to fix this issue so no wonder its working for you. I cant even get the apple geniuses to figure it out. Once apple IDS and phone numbers are unified like they are in iOS6 then it might work. This feature was release prematurely

It took me a few different tries to figure it out, but here is what I did and all my accounts and devices (2 iCloud email accounts and 1 phone number between iPad, iPhone, and iMac) syncing messages perfectly.

With all devices on, I used my iPhone to re enter and re log-in each iCloud account in settings > messages. With each entry, I got a confirmation window on my iPhone telling me that the changes are taking place on my iPad and on my iMac. All devices are receiving and sending messages to each other and from others, using both email accounts and my phone number.

Hope this helps you, and by the way, I am also using iOS 6 on my iPhone and iPad. That may have something to do with functionality as well.

Deep Sleep (Hibernation to HDD) is not working in ML (hangs on restore). Same laptop (MBP '12) had this function working under Lion. I understand this is not a standard feature, but I used it at all my laptops and really enjoyed.

Overall I didn't find ML much different that Lion. If I knew this in advance, I'd probably waited longer before the upgrade.

I liked feedback on ML being faster and more efficient than L, but personally don't feel tangible difference.... Safari 6 is available for Lion as an upgrade. Most of other new features I do not recognize as OS features. Those are just applications that one should be able to download and use.

 

[blueroom]

Doesn't boot on my OCZ Octane S2 (not compatible). Boots on my ancient Vertex 2 though.

 

[Lanarae]

I like Mountain Lion, but the only problem I have are hot corners. Sometime it doesn't work for mission control. I have no problem with notification center or screensaver.

 

[AuPhalanx]

Overall, Mountain Lion has been good for me. The BIGGEST frustration I have is with Mail. They changed how the reply-from address is used, which is a pretty big deal for me. I posted about it here.

https://forums.macrumors.com/threads/1414206/

Otherwise, I'm liking ML. It's odd for me to hop into a point-oh release, but I was feeling jumpy, so I did. I'm not too terribly disappointed. I just hope that they fix Mail.

my problem is with hdmi cable to tv, I am able to watch the exact mirror on tv with Lion, but not with ML.
