    Alright, I now give up on 10.7 completely, and see no reason to "upgrade" to 10.8.

     

    Can someone please give me instruction to go down to 10.6.8? Things that I'm looking at:

     

    1. My drive has several partitions. I thought I was being smart in setting up a 20 GB root partition for 10.7 system files -- I figured that apple's stuff would go there, and my stuff would go elsewhere. HA.

     

    10.7 won't even start unless launchd (1) can find /var/vm, /var/folders, /var/tmp, and a few other things on root before it attempts to mount stuff in /etc/fstab.

     

    So all of that fills up my root almost immediately.

     

    On top of that, the recovery partition is not at the end of the drive where it would make sense, but directly after the root -- suddenly I cannot resize my root bigger.

     

    Combine the battery issue, the "multiple desktops", the lack of a true F8 style control, etc -- and the complete failure of auto-restoration, I want to go back to 10.6.

     

    But I don't know how to reinstall it. The machine is early 2011 (so it can run 10.6), but with the new stuff ...

     

    And the user data. I've got a partition named "/UserData", and my home is on /Volumes/UserData/Users/michael, but it turns out that a lot of apple's data files do not use /Users/michael (my $HOME, and a valid symlink), but wind up hardcoding the physical path -- so just doing a backup, format, reinstall, restore, has all sorts of potential issues.

     

    So, has anyone done this -- wiped 10.7 off and reinstalled 10.6 -- that can tell me what to look out for, what issues, etc -- given that from what I've heard from people, once 10.7 touches the disk, the 10.6 CD can't work with it.

    I've had three batteries in the 3.5 years that I've owned my 15" MBP.  The first replacement was after about 18 months and it was a bad battery that swelled and was replaced (and Apple actually covered about 50% of the cost even though it was no longer under warranty).  Sadly, the second replacement was about 6 months ago after spending 8 months trying to get my battery to hold a charge for longer than 2 hours.  I got slightly better mileage using the graphics switcher and the fan control, but at the same time, why should I have to add anything to a supposedly top of class computer so that its battery will last.  So despite the fact that my battery was still supposedly holding 90% of its charge, it was "bad" and I got a replacement. That replacement has never held a charge longer than 2:15, and I've calibrated it, run it down, shut if off and reboot so that it cycles completely, run all the other PRAM, RAM, BAM, JAM, FAM, FLIMFLAM maneuvers recommended by Apple and every expert (all of whom can come up with no other solution than it must be user error), and still no better than 2:15.  I held my breath for Mountain Lion, but alas, IT IS NO BETTER.  So Apple would rather jam beta testing down our throats than fix shoddy coding. And BTW, I've checked it on console and activity monitor and I've killed plenty of processes that should not have been running but were (poor uninstall setup by Apple, IMO).  Oh, and lastly, I installed ML on a completely wiped HD after a DoD zeroing out of every sector.  Then I installed necessary apps directly first, then some other apps after that, that I had to restore, but mostly clean installs.  So I feel comfortable saying that it's a software/firmware problem, especially since I got 4-6 hours before the Lion upgrades (still crappy compared to advertised, but not bad).  I'm no gamer or video person, but I use the internet constantly.  The biggest commonality, though, is that use makes little difference in how poorly it holds a charge. 

     

    This battery is going back in the next few days.  I'm sure it will be replaced with another battery that still won't last much more than 2 hours.  And this one shows that it's potential charge is about 99% and it's working fine - except it can't hold more than a 2-hour charge.  I own an android phone, and even develop some apps for android, and my silly little phone, with 3D-graphics, multiple apps, and processing with multiple reboots and partitions, as well as purposely abusing/bricking it so I can help people problem-solve their phone issues when an emulator won't replicate a problem, can last 12-13 hours on full tilt, and 15-20 hours if it's idling.  And that's with a 1.2 GHz dual-core processor.  I know the comparison is not truly analogous, but it does mean that my next computer won't be a Mac, when I can get superior quality at a lower price.  That was once not the case, but it is now.

    Do a search on these forums. It is documented over a hundred times.

    Restore your backup.

    i completely understand, but it does hog resources... I choose to turn mine off... I view it as pointless.. though to others, it is necessary.. it will improve battery life though

    I have no problems with battery life, and (for me) indexing is essential, thanks

    Just installed the 10.8 update, I'm seeing 7/8 hours on the battery readings for the first time since Snow Leopard!!! I have only Safari running with medium low brightness. Anyone else?

    you are by far the luckiest person on this thread, how is it that you experience great battery life with mountain lion?

    I get 5 to 6 hours on a 3 year old battery, rennyz27 is not the only one without problems.

    I don't know.. I just installed the 10.8 update which was released to the public yesterday. I heard rumors that the latest update would somehow fix the battery issue.

    Just wanted to chime in, as i have had help form this forum in the past.  Have a MacPro early 2011, 16 GB RAM Lion 10.7.4

     

    noticed heating and very short battery life as described in many posts. Fans running fast,  Battery test and Genius Bar tell me battier is in great shape.  Here is what i did that didnt and then did fix it:

     

    1     tried all the controler resets lists above ...  no help

    2     turned off spotlight on the VM fusion directory .. this was eating a lot of CPU time as it tried to index the Windows OS files.   no real difference.   But a good idea to do anyway.

     

    Then, when using Win7 under VM, the whole windows then Max side came to a screaning halt.  all CPU ticks used and all memory used.  Turns out our enterprise was pusing new software to windows and Enterprise McAfee was running.  I blew a gaskit .. and my IS guy blocked upgrade and took off MacAfee ...

     

    3     removal of enterprise McAfee ... PROFOUND improvement in windows performance.  Some improvment in battery life.

    4.     Genius guy removed all unneeded start up programs ... some help

    4     I noticed a program called VMSCAN.exe or somethign like that running in activity monitor.  using 100% two CPUs ... googled it and it is a VMFUSION MacAfee app.  then i remembered, i OKd it when i installed VMFUSION ...   so i killed it .. had to go on the web to find out how .. you have to login as SU and find the uninstall program ... sorry i cant provide the link ....  this was running eventhough VMFUSION was not ...

     

    Result:  Fans at 2000 all the imte.  Minimal heat.   battery 5.5 to 6.5 hours again !!!!   have been doing fine for a week now. 

     

    Hope this helps someone ... the moral .... McAfee is really really bad.  but we all know this.

    Well this was just posted at Macrumors.com: OS X 10.8.2 Restores Notebook Battery Life to OS X Lion Levels. Not sure if this will make a differnce but I'm about to find out.. I would have been far more excited to read "Restors Battery Life to OS X Snow Leopard" but at least we are headed in the right direction.

    This looks like 10.8.2 does restore it to 10.6.8 levels, and in some cases, it's even better.
