There is something to be said for deliberately stepping into the abyss, confident that, if you need to, you can fight your way back out. However, for most people, Mountain Lion beta is an excellent excuse to finally buy that extra hard drive you've been meaning to get for years.

My personal opinion

Hey all
As a dev and app designer AND just a basic user when it comes to my personal computers (go figure) I can say the 10.8 is behaving VERY very good for a dev1 beta OS

1. Why we throw a beta OS to a working system? Because of curiosity - we want to explore more and more and most of us have no patience.

2. Why that particular person is having so much issues? Most probably he is JUST a basic user and installed from a pirate tracker and wonders why nothing is working after having throw everything possible inside and thinkered the system until it looked like linux or Windows!!!! (he does have windows installed on one partition)

3. My personal belief is that this version so far despite its problems with Flash, Java certain crashes of programs, hungs and critical errors I encountered is working pretty well :) :) :) I am satisifed - the only thing I find not really working is the Notification Center (as a new feature) and also the AirPlay requires you to update your ATV2 to a beta version as well which would possibly mean all devices too WHICH I find to be rather annoying although I can understand the logic in it.



Furthermore I am also currently installing Windows as I need it to run some WinOS programs and I only have a Mac as portable but hey I dont mind reinstalling from scratch anyways.



Has anyone noticed other issues in the stability or maybe some fixes like Mail and Safari incompatibilities?


All the best from me and remember ojc123/macrumors newbie

To those who need help getting Mountain Lion off of that Mac you just installed it on, here is what I did to get this done(Yes, I was one of those idiots who blindly upgraded my base OS..) :)

1. Create a Lion bootable USB drive http://osxdaily.com/2011/07/08/make-a-bootable-mac-os-x-10-7-lion-installer-from-a-usb-flash-drive/

2. Follow instructions and when prompted to install Lion from the USB drive, first go into disk utilities and erase the Mac Hard Drive OS partition (Not the recovery partition even though its now 10.8 anyhow..lol) and run the Lion installer. It should install Lion clean.

3. Boot up into Lion and re-run your patch/updates(as well as re-creating your 10.7 recovery partition which the patching process should do)and when you get to your previous patch level of Lion before you upgraded to ML, you can run Time Machine to restore your junk(or copy/reinstall your junk from an external drive).

This worked for me and I am back on Lion with all my junk with no problems.
Key here is that you can downgrade...There is a way back. lol

I did this and it worked. Mostly. I say mostly because now every time I try and launch the Mail.app it crashes instantly. I had mountain lion for a couple of days and my Time Machine did back it up a couple times, so I think that when I restored my data from my Time Machine back onto Lion it copied over the Mail.app from ML. Anyways, it doesn't work now so who knows.

I attempted to downgrade from 10.8 to 10.7 yesterday. I failed miserably. I believe that 10.8 upgrades the EFI firmware (on the logic board). I believe this is the case because the boot menu (hold alt at chime) has an added "Select Network" option. I could not boot into 10.7. I could only boot to 10.8 and Windows. Anybody telling this guy to "just boot from install disk" doesn't know what they're talking about in this situation. I tried reinstalling Lion three times! Never was I successful in getting Lion to boot (both Time Machine restore and fresh install from DVD).

I think the only way to successfully downgrade from 10.8 to 10.7 is to download the latest EFI firmware update from http://support.apple.com/downloads/ and update the firmware manually through 10.8 and then downgrade via backup or fresh install. This is only a theory (I'm sticking with 10.8 for now).

I agree. I couldn't downgrade when I tried to because the Lion installer kept giving me "Can't download additional components" etc. My internet connection was fine.

I boot up my macbook air with LM pressing the Option button. There is option Mac OS X beside other like 10.8 Recovery HD and Mountain Lion 10.8, but when I go in to that option, it shows up a circle with a slash meaning something is wrong. Does anyone have any suggestion for this. Is this because of the Lion version in my USB thumb drive?
I'll appreciate any suggestion.

really can't go back huh, I went from 10.8 back to 10.6.8 with the install disks..

I think it's you who doesn't know what their talking about..

@OP This is a DP the expectation is that developers will not a: install it as their main OS or b: be able to fix things when/if they go wrong

I have a lot of problems with Mountain Lion. Even if it's a Preview this is ****. I get slow boot up times, it crashes a lot, safari is acting like a bitch (if theres html5 elements the screen flickers from time to time but only in the safari window) then sometimes after 5-10 minutes i cant enter anything in URL bar. The Screensaver doesnt wake up sometimes when i click or press ESC, the laptop doesnt shut down sometimes, the laptop gets hotter as before when doing nothing, its slow with starting, a lot of apps doesnt work right (start and then close 2-3 seconds after it) iMessage is a pice of crap ******** which doesnt work right with icloud. the password remember thingy of safari is bugged. etc etc its just a piece of crap... how can a preview of a better newer version be like 3942387 times worse than the before version???

It is a developer version! NOT a release version. You are expecting too much. Besides, you are a developer, right? So you have another system to work on right? So you are a registered Apple developer, right? The point of a developer preview is to test YOUR software on the new OS version, isn't it? And Apple developers have their own forum to report problems.

Really? As old-wiz pointed out in clear words, it is a Preview, it is like a beta, not a full release where stability is promised. It is for developers, the ones that write software you may take for granted, to test their applications with and report to Apple all the bugs they find, thus Apple can iron them out.
A Preview is not for everyday users. But then again, I like it, when people without knowledge tarnish their systems with a beta they acquired illegally.

And if you were a developer, you would have known better. Ah.

If they were an actual developer they would know better, but clearly their ailment is more that they lack any common sense and were foolish enough to just go right ahead and throw a preview over their existing setup.

So are people actually having this issue when properly partitioning their HDD? I don't get it? Is it somehow dangerous to test ML on a partition? Or are people actually just trying to upgrade their existing main operating system already?

It is not dangerous to use OS X 10.8 Mountain Lion on a separate partition or HDD, but mostly users downloading OS X 10.8 Mountain Lion are just upgrading their Mac OS X 10.7 Lion installation without backing it up before the upgrade. That is the main source of problems, as those users don't seem to know how OS installations work and how to take steps in case something goes wrong, like backups and such.

Maybe, but I backed everything up and that is not the source of my problem, as you seem to imply. My problem is that something happens when trying to re-clean install 10.7 or even 10.6 again, and that is that the installer always fails at the "Can't download additional components..."

Using a 10.6 DVD should provide with the ability to erase the internal HDD and reinstall Mac OS X 10.6 Snow Leopard.
With 10.7 it might be more complicated due to the missing installation medium provided by Apple, that one can "only" use Internet Recovery if one doesn't have a 10.7 installer on a DVD or USB flash memory thumb drive.
When I bought 10.7 I created an installer on a USB flash memory thumb drive using CarbonCopyCloner and I also stored the DMG for future purposes.
Just yesterday I cloned the DMG to another HDD partition to have a bootable installer (I have made an external HDD with ten partitions, four partitions to house all the installers from 10.5 to 10.8m four partitions to house all Mac OS X versions from 10.5 to 10.8 and one partition for mobile backups and one partition for application installers - I did this to have a mobile troubleshooting HDD when visiting clients), and it worked perfectly.

Maybe it is a firmware issue, did your Mac come with Mac OS X 10.6 Snow Leopard or Mac OS X 10.7 Lion?

I made a bootable flash drive like all the other smart/nerdy people, so that's not really an extra pole to jump over.

In regards to firmware: that's exactly right -- i believe it is a firmware issue! I am only posting in this thread so that the guys who idiotically updated to 10.8 without a backup don't feel so stupid. In other words, it lends itself to being empathetic instead of apathetic in regards to their plight!

I can clean install 10.6 using a hard drive with multiple partitions for tech purposes (it has 10.5.5, 10.6, 10.7, and 10.8 DP1). But when I try to clean install 10.7, i cannot. Similarly, if I try to lame-o upgrade install 10.7 from 10.6 -- from the MAS lion app -- i get the same error message when trying to clean install from my bootable flash drive. Note that I have re-downloaded a new copy of lion and re-DMG'd it onto my flash drive with the new copy. Flash Drive works fine; the lion app used to try the upgrade and as a source for the InstallESD.dmg are fine.

I truly believe something happened firmware wise when going to 10.8. No biggie, as it's not that buggy for me, except that a few apps are broken and some other stuff.

This worked for me:

Code:

:)


Edit: Just the "changing the version number" part. I then could start the Lion installer under 10.8.

I managed to downgrade my 2011 MacBook Air to 10.7.3 from 10.8 simply by restoring the OSXInstallESD.dmg from the 10.7.3 App Store download onto an external HDD. Booted from the External, wiped the SSD and then simply installed 10.7.3.

I've had the same issue. This is how to fix it.

If you can do a clean install of Lion, that will help.

Otherwise, just restore to your most recent Lion backup. Then, login as root and you can delete the account. Sometimes it will work and sometimes it won't.

If you did a clean install, just skip that last paragraph. Then open 'Migration Assistant' and do a restore from Time Machine Backup. Then recover your user account and settings. Just check all the boxes. Then after about 4 or 5 hours depending on if its a network drive or not. If it's directly connected to your Mac, it will obviously take less. Reboot. Then do all software updates and you're back on track.

I too have made the mistake of installing developer previews on my main system. Won't anymore.
