Does Logic on Lion offer any advantages over Snow Leopard?

Does Logic on Lion offer any advantages over Snow Leopard? Which is more stable?

Thanks for your replies. I have a new Mac Pro and are about to make a brand new install of Logic. As this is a serious time commitiment, because of all my 3rd party plug-ins, software instruments, sample libraries and loops, I want to choose the right OS from the start so I don't have to re-do it again. I have 10.6.8 on my old machine and that has been working well.
My original plan was to wait for 10.8 and do it then. But now I've read a lot of posts saying people are having trouble on 10.7. For obvious reasons, I would prefer to be on the newest OS, but not at the expense of bugs and glitches. I'm also worried that some of my 3rd party stuff won't work on 10.8. Is there a compatibility list somewhere?
I've been with Logic for almost 20 years now, and my experience has always been that it's usually wise to stay behind at least one OS version, in order to get stability and full compatibility with 3rd party plug-ins and drivers.
Is there any advatage with 10.7 or 10.8 over 10.6 in the way assigning RAM to sample instruments is handled?

  • Does Moc OSX Lion use more battery than Snow Leopard?

    Ever since I have updated my MBP Early 2011 (2.2 Ghz Radeon 6750) to Lion, my battery life has gone down tremendously. I used to be able to get a solid 7 hours in (light workload ei. web browsing) and now I'm only able to get 3.5 hours MAX. I'm currently running 10.7.2 and the problem is still there. I have gone through around 200 cycles so it's not like 1000's of cycles or anything. Is this just me or are other people exeriencing the same problems? I plan on going back to snow leopard soon if there is no fix to this.

    I have had my MBP since July 2011, and am at 22 cycles.
    You must run soley on battery charge, almost never plugged in.
    Are you running your battery very much down (10%-20%) before re-charge , or recharging at about 40%?
    Running Lithium-Ion batteries almost dead create a "memory" that can make your MBP unchargeable. 

  • Can I install Lion over Snow Leopard without erasing and restoring hard drive?

    Been reading a lot about downloading Lion. Recommended to back up hard drive to ext. drive, erase hard drive, install Lion and then re-install apps and files from ext. drive. Can I just install Lion over Snow Leopard without erasing all apps and files on hard drive?

    If you do an upgrade install then be sure to do this first:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Make a bootable backup just in case. Clone using Restore Option of Disk Utility
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.

  • INSTALLING LION OVER SNOW LEOPARD

    I am getting set to install Lion over Snow Leopard (10.6.8).
    Is there anything I need to know about this?  I plan on doing a complete time machine back up before I do the install, on a HD that is internal, anything I need to know about that?  I just want it to go smoothly, any direction and/or suggestions is greatly appreciated.
    Thank you.

    Me, I think clone backups are more useful, and only use T.M. as secondary.
    Using Cloning as a Backup Strategy
    I'd assume that professional apps may need to be tested still; and of course check to see what you have that depends on PowerPC code and Rosetta first. That has some in a tither.
    A clone lets you still be able to boot Snow Leopard. Check out Carbon Copy, SuperDuper.

  • I installed mountain lion over snow leopard and my macbook pro 13" taking time for login and logout,

    i installed mountain lion over snow leopard and my macbook pro 13" taking time for login and logout.. any solution

    Hi JoeyR.  Well, according to this link at the Apple Store, OS X Moutain Lion became available in July and I downloaded it for $19.99.  I figured I would do that before renewing my Norton security SW.  Are we talking about the same thing?

  • Install Lion over Snow Leopard on third party SSD.

    I am currently running Snow Leopard 10.6.8 on a third party SSD (Intel 510 series), and am using Trim Enabler 1.2.  Everything is running well.
    Regarding installing Lion 10.7.2 on the same SSD drive, I have some questions:  Should I simply install Lion over Snow Leopard, then either switch to Trim Enabler 2.0 beta 4, or use Grant Pannell's tips here http://digitaldj.net/2011/07/21/trim-enabler-for-lion/.  I have read in places that it is best to perform a wipe or some type of reconditioning of an SSD before installing Lion on it.  Thanks for any advice you all may have.

    I would do the following:
    1) buy an external disk enclosure with USB and/or FireWire interface
         http://www.newegg.com/Product/Product.aspx?Item=N82E16817146604
    2) buy a cheap traditional hard disk at least the same size as the SSD or larger
    3) Clone the SSD to the external hard disk inside the enclosure
    4) Download Lion from the App Store and copy the installer to a USB Flash Drive
    4) Delete the partitions on the SSD (don't bother formatting)
    5) Install Lion cleanly with a boot USB Flash Drive
    6) Connect the external disk and use the Migration Assistant to move your data back
    7) Once you are sure all is good (take a few weeks to be sure) then you can format the external disk and use it as a Time Machine drive.  Or use it for other purposes.
    Give it time to index everything with Spotlight.
    That would be the most clean way to upgrade.  Some have been lucky with Lion upgrades but if you have a ton of legacy stuff installed as well as custom tweaks, etc.  Then you are likely to run into issues.  Best to start clean and neat and migrate your data over.  I would even re-install the Apps individually. 
    Make sure you are not running any PowerPC Apps which rely on Rosetta because that won't work in Lion after the upgrade. 

  • I have just installed Mountain Lion over Snow Leopard, I now can't open Photoshop?

    Hi everyone, I have just installed Mountain Lion over Snow Leopard. The installation went smooth and woks well. Now I find that Ican't open either Photoshop CS or Microsoft Word. I upgraded in order to install Lightroom 5, obviously there is now an incompatability, is there a work around?

    If that is the original Photoshop CS, and Word 2004 or earlier, then they won't open because Lion and Mountain Lion do not support PowerPC apps. They must be Intel code. Snow Leopard could run them because it included Rosetta, a PowerPC to Intel (and back) interpreter.
    You have a few options.
    1) Go back to Snow Leopard.
    2) Update your apps to compatible versions.
    3) If you have Mountain Lion because newer apps require it then:
    a) Install Snow Leopard Server (currently being sold by Apple for $20) in a VM such as Parallels, and then run your PPC apps in the VM.
    b) Install Snow Leopard on a separate partition and boot to that version of OS X when you need to use those older apps.

  • What are you doing with software (games) designed to run on Snow Leopard.  Have you heard of anyone making a patch for LION?

    What are you doing with software (games) designed to run on Snow Leopard when the Os is Lion?

    It is up to the publishers of games to accommodate their software to Lion.
    Blizzard, publisher of StarCraft, WarCraft, and Diablo, has posted a statement about that -
    Blizzard Support
    Although they were able to create patches to allow the use of their (OS 9) games in OS X up through Snow Leopard, apparently from their perspective it is not possible to patch those games for Lion.

  • About installing Lion over Snow Leopard from an external Hard Drive

    I was just talking with an Apple Representative on the phone a bit earlier and he said that if I connected up to a computer with Lion on it already, booted it into recovery mode, then installed Lion onto an external HD that I could then attach the external HD with Lion on it to a Snow Leopard machine and boot off of the Lion Partition (on the external HD) and then I could upgrade my sno leopard machine from this lion "image" on my external Lion drive.
    My question is that will this keep all of my files on my Snow Leopard machine in place (so basically will this perform an upgrade) or completely erase everything off of my Snow Leopard machine?

    To boot from an external optical drive:
    Boot Using OPTION key:
      1. Restart the computer.
      2. Immediately after the chime press and hold down the "OPTION" key.
      3. Release the key when the boot manager appears.
      4. Select the desired disk icon for the external optical drive. The DVD
          should be in the optical drive before restarting the computer.
      5. Click on the arrow button below the icon.

  • I have a sonos music system that does not yet work with Lion and will not for about 3-weeks.  I need to uninstall lion and go back to snow leopard, how do I do that?

    I have a Sonos music system that is not yet compatible with Lion and will not be for several weeks.  How do I uninstall Lion and go back to Snow Leopard?

    While we all have MacBooks only a few have Lion. There's a Lion Support Community. You should also post this question there. https://discussions.apple.com/community/mac_os/mac_os_x_v10.7_lion

  • How can I unistall Lion and go back to Snow Leopard?

    I upgraded to Lion (stupidly and blindly) and now most of my programs are not compatible.  What is the process to go back to Snow Leopard?

    Given the lack of response to this particular discussion, and given all the various and sundry ideas on this topic, I have had a panic-stricken 48 or so hours since I asked my question.  Here's what finally worked to get me back to normal:
    1.  First, I gritted my teeth and erased my hard drive, hoping and praying I'd be able to restore from Time Machine.  I'd been backing up for quite some time, but never needed it before.  HOWEVER:
    Lion evidently left little gremlins all over my hard drive, because I simply could not get my hard drive restored properly, not from the Time Machine restore function on the SL disk NOR from a manual  "Star Wars" pick and choose with my Time Machine.  Therefore (and this is important):
    I zeroed out my hard drive completely, after trying for an entire day to get things back to normal.  What you have to do is start up from the Snow Leopard disk, and do a COMPLETE erase, by which I mean that when you use DU to erase your hard drive, you go into the "security" panel on th DU screen and do a 7-pass zero-initialization of your hard drive, i.e., write zeros all over everything on your hard drive seven times, leaving it truly free of that yucky Lion.  THEN I reinstalled Snow Leopard, ran Software Update several times until it had updated everything it wanted to ad nauseum, and THEN was able to get Time Machine to work properly and bit by bit restored everything I wanted to restore.  I am appalled at the lack of accurate documentation that comes with Time Machine, frankly.  Anyway, when you get ready to restore your software AFTER you put the Snow Leopard system back on your hard drive and update it, you have to go back to a backup from BEFORE you installed Lion, though:  this is important.  Don't try to put anything associated with Lion back on your hard drive.  For me, that backup was done was last Friday.  It took ages, but....my hard drive is now purring like a kitten, and I have Snow Leopard and all my old software back.  It was a mess, but it seems to be over.  I learned from this disaster how important it is to completely wipe your hard drive clean before trying to reinstall an older  operating system.  As far as Lion goes, I will be extremely careful before I assume any new upgrade is a good upgrade.  It isn't.  I LIKE my elderly Adobe programs and my kid likes her games that need Rosetta, as does Word 2004.  My Mac is much happier with Snow Leopard.  For now.  If it ain't broke, don't fix it.

  • How do I remove Lion and go back to Snow Leopard OS?

    How do I remove Lion and go back to Snow Leopard?

    If you have the white upgrade disk (originally, you had Leopard and bought SL later), easy. I'm not sure if you have the grey disks (you bought the machine with SL).
    If you have the white disk, the first thing you do is get a USB external HD. Format it to GUID with disk utility.
    Insert the white SL disk and restart. Follow the instructions to install SL on the external disk.
    Have a look here for a step by step tutorial for setting up the external HD: http://www.maciverse.com/installing-snow-leopard-onto-an-external-hard-drive.htm l
    From here on in you have two choices:
    1. You can run SL off the external disk and keep Lion and all your files/data on the internal disk.
    This is the easiset thing to do. You can open files from your Internal Lion disk by navigating through to it in Finder when you're booted in to SL on your external disk. Practical if you have a desktop machine, maybe not if you have a laptop that you need to carry everywhere (you'd have carry the external HD with you all the time).
    Any non-Lion only (i.e., not Safari, Preview, Terminal and Mail Lion upgrades) apps should also run off your Lion disk when you're booted into SL, but if you have any problems, just drag them from the Lion Apps folder to the SL apps folder.
    2. Move everything over to the external disk if you plan to install SL back to your internal disk.
    Start copying over all your apps and files manually by dragging them from the internal disk Apps and Folders to the external disk Apps and Folders. If you have Time Machine, you can also copy your files by navigating to Time Machine through the Finder rather than trying to use the Time machine interface.
    You might spend some days doing this, but it's worth doing it manually. When you're done and sure you have everything, google 'Carbon Copy Cloner'. Download it (its free), and clone your external HD to your internal HD. SL restored!

  • Battery discharge: Lion 10.7.2 vs Snow Leopard 10.6.8

    Has anyone noticed that Lion consumes more resources than Snow Leopard thus causing faster battery discharge?
    YMMV, but it would be interesting to see of others can get similar results. Do you suppose Lion 7.3 will increase or decrease resource usage and what affect will it have on battery life?
    I called Apple about the battery discharge issue on my 2 week old MacBook Pro with Lion 7.2. I was only getting about 1/2 of the 7.7 WIFI hours advertised. They gave me the usual "if depends" on WIFI, system settings, applications, etc., i.e. such things as cpu and memory load (paging/swapping=>disk i/o), other disk activity, and a few other things.
    My large expenditure on the new MacBook spurred me to investigate what was going on using the Activity monitor. I configured my old MacBook Pro (mid 2009) and my new MacBook Pro (late 2011) with the same system preferences. I reset both the PRAM and SMC on both machines to maximize the battery charge (documented elsewhere).
    Obviously, a direct hardware comparison would not be meaningful but when you look at the operating systems there is a significant difference between Snow Leopard OS X 10.6.8 and Lion OS X 10.7.2. Lion uses much more resources than Snow Leopard.
    My Observations:
    The first value I list is for OS X 10.6.8 and the second for OS X 10.7.2. I tried numerous other combinations but these nicely summarizes my results.
    1) I started with only the Activity monitor, iTunes Helper, and Epson EEventmanager manager running, No WIFI or any other user processes
    CPU % idle               : 98.75 vs 99.4 (i.e. both machines were literally idle)
    No. of threads           : 179   vs 277  --> + 55%
    Kernel threads           : 60    vs 82   --> +37%
    Processes                : 41    vs 54   --> +32%
    Wired Memory MB          : 480   vs 864  --> +80%
    Active Memory MB         : 198   vs 407  --> +106%
    Memory Used  GB          : 0.808 vs 1.32 --> +63%
    Percentage of 4 GB       : 20%   vs 33%  --> +65%
    Virtual Machine size GB  : 96    vs 149  --> +55%
    2) With WIFI and Safari added
    CPU % usage              : 72.9 vs 91.02 (i.e. both machines were not very busy)
    No. of threads           : 253  vs 376 --> +49%
    Kernel threads           : 60   vs 82 --> +37%
    Processes                : 51   vs 63 --> +24%
    Wired Memory MB          : 669  vs 1007 --> +51%
    Active Memory MB         : 600  vs 1190 --> +98%
    Memory Used  GB          : 1.57 vs 2.47 --> +57%
    Percentage of 4 GB       : 39%  vs 62% --> +59%
    Virtual Machine size GB  : 131  vs 191 --> +46%
    Look especially at the percentage of memory used. In either case, I measured no paging nor swapping. But, as you can see, with the increase of memory used with Lion when WIFI and Safari were added you could quickly push the memory as more process are added and start paging and swapping to/from disk hence use more battery charge.
    The increase in number of threads, processes, memory usage, virtual machine size, and WIFI activity would imply that Lion would have to consume more battery charge than Snow Leopard as you use more cpu/memory to chase more threads.
    I looked at WIFI usage and it involves a lot of chatter between the computer and the internet. Over time a lot of packets are sent/received even when no data is being passed and would be a drain on the battery. There would be a greater drain when there is data passed because of the additional CPU and memory needed. But, in todays world, you cannot run without an ethernet or WIFI connection because of the dependency on the information/data on internet cloud.
    Hardware:
    MacBook Pro 13", mid 2009, OS X 10.6.8, 2.5 GHz Intel Core 2 Duo, 4GB 1067 MHz DDR3, 5400 rpm Hard Drive
    MacBook Pro 15", late 2011,OS X 10.7.2, 2.4 GHZ Inter Core i7, 8 GB 1333 MHz DDR3, 7500 rpm Hard Drive

  • How do I disable Lion and go back to snow leopard

    I up graded to Lion. Now my wireless router can't connect because it doesn't support Lion. I don't want to have to buy a new router.
    Can I disable lion and go back to snow leopard?
    P.S. I am new at computers so be easy on the terminology please.

    It would help if you gave some information on WHY the router isn't working. Start with the basics:
    -What brand and model is the router? If you can get a version number, that is also sometimes helpful. This info is generally printed somewhere on the router, usually a label on the back or bottom.
    -What do you mean by "doesn't support" - did you get this info from the manufacturer, or is this based on you not being able to connect? Routers use standard wireless protocols (called 802.11a/b, g, or n). The network cards in Mac computers also use these same protocols.I can't think of a reason why it shouldn't work.
    -Does your router have a wired connection? If so, can you connect with an Ethernet cable? You may need to be able to connect to the router directly to change settings.
    -How old is your router? And have you ever tried to upgrade the firmware settings on it?
    -Can you connect to ANY wireless routers anywhere else with your Lion computer?
    -Do you have any OTHER computers (Windows or Mac) that can successfully connect to your wireless router?
