Why is searching so much slower in both Lion and Mountain Lion than Snow Leopard?

Hi, I use Snow Leopard run on several Mac Pros to perform multidimensional time-lapse-imaging in our lab. Snow Leopard provides instantaneous (seconds) searching for folders containing the image sequences I require for analysis (distributed across 4 x 2TB hard drives- images are saved under the structure Time\Position, and for analysis I need to retrieve all folders with the same Position label). Lion and Mountain Lion either fail to search or are painfully slow. For analysis I use internal hard drives connected as external volumes via USB and I suspect this might be part of the problem, however the same setup works flawlessly with Snow Leopard.
This problem is becoming very frustrating as I can’t figure out what has changed, or whether I am overlooking something obvious. I installed Lion on my MacBook Pro over 6 months ago which is when I discovered this problem and had to reinstall Snow Leopard. At that time I had hoped that the next OS might provide a better search function for our use, but after some testing it seems the same. To search through folders manually takes over 10 x as long as using a simple search in Snow Leopard. Can anyone provide me any advice as to what might be causing this problem and whether there might be a solution? I’ve tried a few free searching tools from the app store, but these do not perform any better than searching in Finder. I would obviously prefer to be able to invest in new Macs in the future which run the most current OS without having to install Snow Leopard on them all (if this is even possible without future models without causing compatibility problems).
Many thanks for reading and for any advice you can give me.

Why can a person buy and/or download Snow Leopard, Lion, and Mountain Lion but not Mavericks???

I am running OS X Lion on a mid 2009 MacBook Pro with 4GB of ram and a 160GB HDD. I was going to download Mavericks from the app store but waited to long. Now that Yosemite is out Mavericks has disappeared from the app store. WHY? A person can buy and/or download Snow Leopard, Lion, and Mountain Lion but not Mavericks??? And the kicker is that it was FREE!!! I just wanted to load Mavericks on my MacBook Pro to see how it performs. If I could live with any slow downs or quirks, I'd leave it installed. If not, I'd roll my system back. Apple's policy of ramrodding unstable product down our throat is BS. I don't want to use Yosemite until it has become more stable!

Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase a redemption code at the Online Apple Store: OS X Mountain Lion. Mountain Lion is $19.99 plus tax. Use the code to redeem a download of Mountain Lion from the App Store. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

Have a MacBook Pro running Lion and an IMac running Snow Leopard. Want to Back up both images and restore on opposite machine. Essentially swapping images between hard drives. Is this possible and any "gotcha's" to look for? Thanks

Have a MacBook Pro running Lion (10.7.9) and an IMac running Snow Leopard (10.6.8). Want to Back up both images and restore on opposite machines. Essentially swapping images between hard drives. Is this possible and any "gotcha's" to look for? Thanks

If the MBP came with Lion, it most likely won't boot with SL. Easiest thing to do is create a bootable backup/clone of each to an ext HD, partitioned to hold each on a separate volume, ensure that the original machines can boot with their respective clones, and finally, try booting the other machine with the other clone. Images are useless since you can't boot with them to test them out.

I am running OSX 10.5.8 on a 2008 Imac with Intel Core 2 duo am I compatible with OSX 10.6 snow leopard, much less Lion and Mountain Lion?

I want to link all my apple products so I can use icloud with ease but I am running OSX 10.5.8 on a 2008 imac with intel core 2 duo and not sure it's going to be beneficial or compatible. Is my desktop really just an external hard drive alreadt in 5 years? I just purchased a mac book pro 2012 and also have a 3Gs iphone I just want to have a happy apple family ; )

Your computer is compatible with all of those OSes, but may need more RAM to run 10.7 or 10.8. As the RAM requirement is the same for both 10.7 and 10.8, don't bother with 10.7 unless you're using software incompatible with 10.8.

How much space does Lion and Mountain Lion take up?

I have a 64gb MacBook Air and I dont have many apps or files on it but I only have 30gb left, is this normal?
I'm new to Macs

Why do I have to buy Mountain Lion and Mountain Lion server to upgrade my Lion server?

Hi !
I can't find any option in app store to direct buy OSX Mountain Lion Server to upgrade my Mini i7 Lion Server ?!? Just necessary purchased the Mountain Lion and BUY AGAIN OSX Server Packet $19, billing Twice ?!?!

You are looking at a radical change, 10.8 Server is not an "Upgrade", it's an application. The previous Apache is still at its old location but is unused xcept for some .conf files. The arrangement and configuration of 10.8 Server.app is a big change from 10.7 so plan on some relearning. You will buy the application Server.app which on first run installs components at /Library/Server/*. Most everything is now inside the Server.app package in the Applications folder including all scripts for Wiki pages and several Apple specific Apache modules. Apple is also replacing the messy *.conf flat text files with plist files so that is an improvement. In addition, Python script support is now built-in as well as WSGI for those running Python webapps.
Having said that, some parts have sharp edges so don't expect full operation for a few versions.

Why is Mac OS X 10.7 so much slower than Snow Leopard? It isnt smooth, applications are slow and most dont respond, and dowloads take hours, minutes.

Something is seriously wrong with your installation or you are critically low on RAM, like below 2 GB.
How much RAM is in your machine?
Have you tried a Recovery?

Since loading Lion, I've experienced much more instability than Snow Leopard. In particular, Mail crashes with regularity, full-screen apps seem to run slower and show the beach ball more often for longer, etc. I'm disappointed with the performance. Any

Since loading Lion, I've experienced much more instability than Snow Leopard. In particular, Mail crashes with regularity, full-screen apps seem to run slower and show the beach ball more often for longer, etc. I love the features, but I'm disappointed with the performance. Any help coming from Apple? I've been sending them so many reports after crashes, that their file must be full!

Summoning max. courage, I did what you advised. Here is the result. What does this tell you? My Lion 7.2 (mid 2011 iMac) has several annoying glitches (which I have so far tolerated through gritted teeth) but none that have actually stopped me working.
BTW, I see several items involving CleanMyMac which I did not know I had. It is generally villified as a trouble-maker. Spotlight can't find an app. or a utility of that name. How can I get rid of what's there please? Just delete?

Why is my mac so slow i have cleansed and cleaned it is a 2010 mac mini i5 but it runs like a 20 year old pc i have only had it for a few months and it was straight out of the box

I'm thinking that you have a > Mac mini (Mid 2011) - Technical Specifications because the 2010 model's only have Core 2 Duo processors and the 2011 had the first i5 processor.
2 GB of RAM is the minimum requirement for Mountain Lion, but it's hardly enough to really enjoy doing anything else.
see > Memory and Free Installation Guides for Apple Mac Mini
Plus I don't have any problems running Mountain Lion and a load of App's on my 2010 Mac Mini with 8GB of RAM.

I recently updated? to Lion from 10.6.8(snow leopard), and things seem to be running slower. Has anyone had similar problems? I have Feb 2011 Macbook pro 13" 2.3 Ghz.

As Shootist pointed out, the system uses more power.
However, initially it will reindex the hard drive for spotlight, which will slow things down temporarily.
It also must rebuild caches that eventually will speed things up.
If it has completed indexing the hard drive (no dot pulsing in the spyglass), then there might be something wrong.
Start by booting into the Recovery HD (a partition created with Lion that has Disk Utility and reinstallation options) by holding down cmd-r when you restart. You can let go when the gray screen appears.
When it boots, select Disk Utility and Repair the drive.
If that doesn't speed things up, try re-installing the OS from the same Recovery HD. It won't delete any of your files, but it has helped some people whose Macs ran slow after installing Lion.
Also, how much memory do you have? Lion needs RAM so maxing your Mac out might also help.

Logic Pro slow after SSD and mountain lion update.

1 week ago i was mixing a project of 90 tracks, and every run really well, no "system overloads" at all.
Sometimes the 320gb 5400rpm HDD give away a message that it was running a little slow and had a hard time dealing with all the 90 tracks, but it still work'd well.
3 days ago i installed a new samsung 830 256GB SSD and updated from lion to mountain lion and wow!
Everything is really fast, except logic pro.
Im now running a project with only 35 audio tracks with EQ,compressor and 2 busses with reverb.
It should work fine, SSD with 2,3 dualcore i5 cpu and 8gb ram but no, i am only able to play a quarter of a secound before i get the anoying "system overload" message....
Does somebody know what could be wrong? Mixing is my job soo this is a real problem for me.
Thanks!

Are you getting sudden motion sensor related stops? It may be best to tern your SMS off, as there is no need for SMS in a drive with no moving parts.
They would look like the error here

if there is no mention of the SMS I wouldn't bother although, no harm would be done if you did anyway.
You disable SMS by doing the following:
Launch Terminal
Type the following at the command line: sudo pmset -a sms 0
Hit return and enter your password

Time Machine Backup is slow (perhaps corrupt?) after Mountain Lion upgrade

Hello!
I managed to download and upgrade from Lion to Mountain Lion yesterday. Before the upgrade, I performed a backup via TM just in case. Now, in Mountain Lion, the backup prepares and begins around 12GB of backups but never gets passed 2MB of data transferred. The TM logo keeps turning, the external HDD is clicking and the activity light is blinking to indicate communication.
I vaguely remember having a slow backup after upgrading from Snow Leopard to Lion, but never *this* slow.
Has anyone else encountered a similar issue or know of any diags I could do? As a prerequisite to this, I have attempted to verify the disk in Disk Utility but it seemed to be taking a long time (around 2 hours without completion) to verify, too.
Thanks =]

I am also experiencing very slow backups since upgrading to ML. You didn't go into specifics on your hardware setup (type of machine, backup drive, etc).
I'm using a MB air (Mid 2011) with a Thunderbolt display. I have a G-Tech 2 gig external drive connected with Firewire 800 through the Thunderbolt display.
My backups had always been pretty quick. Now they can take up to half an hour or longer depending on the amount of data to be processed.
One suggestion for you is to obtain a time machine log viewer. I use "logviewer for time machine" that I got in the Mac App store. I think it is $0.99, but there other apps that are available for free. This is nothing more than a log viewer that you refresh and see each step of your backup including any errors. A lot better than right clicking the spinning circle around the clock in the menu bar for status updates.
I am baffled on why the slowdown. I am think of opening a case with Apple Support.
Take care

I have a MacBook Pro (15-inch, Late 2008) and am currently running Snow Leopard 10.6.8. I would like to know which is the most stable upgrade for my model. I have read some reviews of Maverick and Yosemite making the older macs slower. Is this true?

I have a MacBook Pro (15-inch, Late 2008), Intel Core 2 Duo 2.53 GHz, 4GB Memory. and am currently running Snow Leopard 10.6.8.
I would like to know which is the most stable upgrade for my model? Mountain Lion, Mavericks or Yosemite?
When I had gone to the apple care centre in India a few months ago to upgrade my OSX to Mountain Lion, I was told that considering my macbook pro's specs, upgrading it would just make it less efficient, and that I should stick to Snow Leopard unless I consider buying a newer mac that would benefit from it. Is this true? I find it a bit hard to believe. Which update is most recommended?
I also notice that my mac has gotten considerably slower. While using chrome, it buffers and struggles with even just 5 tabs open. Could this have something to do with my current ios? As a precaution, I have always been making sure I have enough free space on disk i.e around 70 - 100 free out of 250GB.
Any advice is appreciated.
Thanks in advance.

Mavericks is no longer available from the App Store, so your choice is Yosemite. One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won't have to go though the revert process.
Check to make sure your applications are compatible.

I need to have both Snow leopard and Lion...Mountain lion running on my iMac. How do I install Lion or Mountain lion on an Ext H D and boot from it?

My software is obsolete (and now dead) in 10.7 so I need to keep Snow leopard alive to run that- but now things like TurboTax are dropping support for 10.6 or lower and I have to have lion or Mountain Lion available. I actually downloaded Lion onto a thumb drive but never installed it when I found out that it would immedaitely render all my FreeHand files inaccessible (years of work!), Now that I am forced to have an OS above 10.6 I was hoping I could install whichever--Lion or Mountain Lion onto an external hard drive and figure out how to boot from that (found something in archives I think, but I need words of one syllable or less). This way I could, ideally, boot from either the External hard drive in the higher OS when needed, or from the internal hard drive when I need to use Snow leopard. There is a long story here, but I think this is the gist. I wasn not sure if this should be asked here or in either Lion or Mountain Lion (both of which I have, essentially, ignored since I would not be moving up until I could figure out how to access those old files of forms and drawings00but now I have no choice. I am panicking now that I HAVE to make the move anbd cannot afford to buy another Mac just to keep two separately running. Any help would be greatly appreciated. i asked Apple when Lion came out and they said there was no way to partition (even if I KNEW how to do that) the haaard drive and install both on my iMac-- but I "think" this is a bit different and possible??? Thanks (once/if I figure this out, I need to figure out how to back-up but that is another matter)

You need to move to Windows 7, because Apple is now releasing a new OS X version annually and it's playing havoc with people's hardware and software.
Windows 7 will get support until 2020, that's 8 years of software stability, however you do need to make System Restore disks, boot disk and another on a hard drive to self restore (like TimeMachine is for OS X)
Apple has no plans to change their currrent behavior as all they care about is selling new hardware with a shiny new OS X verison on it.
If you wait to move, what will happen is you'll lose that full 8 years and will have to swtich to a newer Windows sooner
Windows 7 machines are still widely avaialble, despite Windows 8 (a failure) being pushed currently.
Running three OS X operating systems on one machine is quite a chore reserved for only seasoned computer geeks, then it's only going to last X months as the next OS X version will be released, then the next a year after that.
Another method would be to get a virtual machine software (virtualbox is free) and install Windows 7 into that to ease your transitition if you cant' spring for a Windows 7 machine, preferablly a tower that will last a long time.
Here is a method to run Snow Leopard in Parallels, however it's a unapproced hack and not for the comptuer newbie.

We have no control over Apple's OS X release cycle, nor the third party developers who make their own decisions what to support.
Our only choice as users to stop using both products and seek software/hardware stability.

iPad IOS 7.0.2 and Mountain Lion 10.8.5 Calendar colors do not match between computer and device. Problem did not exist until updated IOS arrived. Colours change of their own free will despite being corrected on both iPAD and MacBook Pro. Any answers?

Please do not post the entire messages log as it takes up unnecessarily a lot of space. It seems that there is a corrupt/nonfunctional file called
[email protected]nt.plist
Go to your hard drive, enter library, go into users, and go into launch agents and delete the thing above. Empty the trash and restart.

Why is searching so much slower in both Lion and Mountain Lion than Snow Leopard?
