Opinions on Snow Leopard

I'm currently running OS X 10. I went to the Apple Store to buy the OS X 10.6 Snow Leopard upgrade.. that was until I read the reviews. Over half of them say that 10.6 is horrible, while the rest (the minority) say it's amazing. After all the similar warnings about how people's Mac's ran great up until installing 10.6, I rethought my decision to upgrade. My main reason for upgrading is because there are more and more software updates surfacing that require 10.6. I'm starting this thread to get some more opinions on Snow Leopard, so I can figure out if I should upgrade, or stay where I am.
Thanks,
-Adam

The $29 version (single system: http://store.apple.com/us/product/MC573Z/A) or $49 version (5-system family pack: http://store.apple.com/us/product/MC574Z/A) do both clean install and upgrades. The only real question for you is whether you buy a family pack just because you might upgrade more systems and the price is less than 2 single-system disks or spend $29 and be limited to 1 system install.
1 external drive, and your choice of disk (1 or 5 system). Done and done.
OWC (macsales.com) is a vendor that tries to be Mac compatible and carries many external drives that are trusted by others in this forum. Choice of interface (USB or Firewire) and size is up to your budget. And whatever drive you buy can become a backup drive when you decide to commit to one system or the other. Or stays the separate system if you decide that Leopard and SL both offer good reason to keep them around for application compatibility.

Opinions on best install method for Snow Leopard

Good morning. I've pre-ordered the family pack for Snow Leopard. I have many applications, music, etc. on my various Macs and am just wondering, in the opinions of the masses, what is the best suggested installation procedure to use for Snow Leopard? Archive and install? Or something else?
Thanks for the input.

It takes out the "code" redundant for snow leopard. I would think this is the PPC code taken out w/c makes sense because if you look at this way. Its not compatible for PPC anymore. Its much faster. So all the kernel files and system files will all be intended for intel. Data files(music,preferences,movies,pictures etc..)will not be affected

Opinions please on Lion or stay with snow leopard.

I have a 24in imac with a 2.8intel core 2 duo w/ 2 g of ram. Everything works perfectly now and after weeks of browsing the discussions and the web I am really afraid to upgrade to lion. The only reason I might have to is because of all my .mac /.me mail accounts. After years of use most of my mail accounts are with mobile me and I would be lost trying to change everyone of them. I moved all my galleries to Picassa and I never used idisk. Does anyone with this computer and processor have anything encouraging to say about lion? Many have said it slowed their computers down considerably. Thank you for any advice.

Lion will not slow down your computer unless you do not have adequate RAM. 2 GBs is the required minimum, but practically you need at least 4 GBs. That said unless you have some specific need to use Lion there's no need to upgrade. Eventually you will have to if you want to use iCloud.
How to Install Lion Successfully - You must have Snow Leopard 10.6.7 or 10.6.8 Installed
A. 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. Then select Disk Utility from the Utilities. 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. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.3.) if DW cannot fix the drive, then you will need to reformat the drive and reinstall Snow Leopard.
B. Make a Bootable Backup 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 backup volume. Source means the internal startup volume.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade to Lion:
Purchase the Lion Installer from the Mac App Store. The download will start quickly. Lion is nearly 4 GBs so a fast internet connection is essential. Download time could run upwards of 4 hours depending upon network conditions and server demands at the time.
Boot From The Lion Installer which is located in your Applications folder.
Follow instructions for installation.

Is it worth it to update from Snow Leopard to Lion?

I just got my first Macbook (early 2008 edition for maximum savings moneywise), and I found out that I can't sync my iphone 5 and ipad mini on the Leopard OS that is on it. I've already worked out that I have to at least get Snow Leopard to use my devices, but someone also told me that Lion is better than Snow Leopard. Any opinions on if it's worth going to Lion instead of just Snow Leopard? And would it COST MORE? Thanks for any opinions, this is the first time I've used a mac since Computer class in 1993 in Middle School so I'm a little confused with some things...

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 Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading from Snow Leopard to Lion or Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mavericks- System Requirements
       Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later

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 by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. 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.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.

Installing Mountain Lion from Snow Leopard, Install failed and HD write-locked

I recently downloaded the mountain lion installer from the App Store and I ran the installer. Stupid person as I am, I did not have any backups for my file and I naively assumed that an apple OS installer would be without flaws. Boy, was I wrong. I need every bytes of my data (or close to every bytes) but the installer failed.
Mid installation, the installer stopped and said that the installation failed and that I need to repair my disk. So I restarted the computer and I ran disk utilities (my start up disk was the OS installer and the installer allows me to run several programs, including terminal, disk utilities, and by the way, when I held option while starting up to see which start up disks I have, I only had the OS installer as the start up disk. Also, the installer allows me to run a program called "Startup Disk" when I click on the apple logo on the top left corner, but it doesn't allow me to startup my computer using Macintosh HD) and noticed that when I highlighted Macintosh HD, my "Repair Disk" button was grayed out. So first things first, I ran the "Verify Disk" button but after a minute or so, Disk Utilities said that verification failed and that Macintosh HD needs to be repaired. But the "repair disk" button is grayed out! So I went to the Mountain Lion installer again and ran it. Of course, it failed again so I restarted the computer.
So I tried to first back up all files in Macintosh HD to an external hard drive using Disk Utilities, and I used features such as "New Image" and "Restore" but they both ended up in "Input/Output error". I tried many methods with Disk Utilities but they resulted in errors.
After some research, I noticed that some people's computers worked after they reset their PRAM. So that's what I did. I held command+option+P+R when computer started up and I reset the PRAM. When the start up disk (which is the OS installer, not the normal operating system) loaded, I was greeted with choose languages option and then I was back in the Mountain Lion installer state. I again ran the installer again, hoping something would be different, but then it was different. But not in a good way. When I was told to choose where I would like to install Mountain Lion, I noticed that Macintosh HD was grayed out. Last time, I was at least able to run the installer but this time, Macintosh HD was grayed out. The installer said that my Macintosh HD was locked. After some research, I learned that apparently, the Mountain Lion installer write-locks Macintosh HD mid installation.
So now I am stuck and I am thinking of two things (plus some questions)
1. I am wondering if there is a way to unlock Macintosh HD. But even if I can unlock Macintosh HD, there is no guarantee that the installer will successfully install Mountain Lion, am I right?
a. so how can I un-write-lock Macintosh HD?
2. More realistically, I am thinking of borrowing someone else's macintosh computer and use it as the backup center. I have a firewire cable and a terrabyte external hard drive. So what I'm thinking is that I'll hook my computer in target mode to my friend's computer and I will also plug in my external hard drive to my friend's computer and then I can download and run Carbon Copy Cloner from my friend's computer to copy all data from my Macintosh HD to my external hard drive. And then I will erase my Macintosh HD, freshly install Mountain Lion onto it and then copy all data back from my external hard drive. But I am not sure about few things.
a. it looks like my Macintosh HD is write-locked. Can I still use Carbon Copy Cloner to copy all data from Macintosh HD (in target mode) to my external hard drive?
b. will my computer allow me to erase (or format) Macintosh HD?
c. will my erased/formatted Macintosh HD able to install + be installed Mountain Lion OS?
If you are here, then you have read my long long problem. Thank you very much and I would really really really appreciate your answers and opinions. Thanks

I'm not sure where you read that about the disk being "write-locked." That doesn't make much sense, given that the major task an installer like this must achieve is writing a whole bunch of files to the hard drive. I think your source was mistaken.
As to what happened, it sounds like your hard drive was badly corrupt to start with, or possibly was on the edge of failing and is now in the process of dying entirely. If you don't have backups of your data, that does not bode well for you, unfortunately. If you can manage to use target mode to copy your data, do that.
Once you're sure you've got all your data, you need to start up from your Snow Leopard install disk and repair the hard drive. (Since it sounds like the Mountain Lion installer didn't work, I wouldn't trust the recovery partition that Mountain Lion installs.) Or, even better, just erase the hard drive entirely and reinstall Snow Leopard. Then, once you're back up and running, with all your data back on the system and with Snow Leopard updated to the most recent version, try installing Mountain Lion again. If any of that fails again, the problem is likely to be a dying hard drive, and you'll need to replace it.

Snow Leopard Time Machine - Backup to a Network Drive is it possible?

I have a MacBook Pro 17" 2.5Ghz, with a 250gb harddrive, running Snow Leopard 10.6.1. I want to do a clean reinstall of Snow Leopard and I want to run a backup first. I don't have any external drives big enough for the job, but I do have network drives that have enough space. Can anyone give me directions on how to set up Time Machine to work with network destination drives? I read an online article that it was possible to do this with Leopard, though I never got it to work. If all else fails, I'll have to buy a new external drive. (Money's tight right now though.) If any of you have recommendations for good fast external drives, I'd appreciate your opinions on that too. (But I really hope I can get the network drives to work.) Thanks!

Time Machine does not back up to network drives, except Time Capsules or a drive running Leopard or Snow Leopard on another Mac on the same local network. It will often back-up to a USB drive connected to an Airport Extreme, but even that is, technically, unsupported, and may require running a special Terminal command to make it work.
Here's the official word: http://support.apple.com/kb/HT1733
You may find some hardware or "hacks" that might make it work, in some cases, to a degree. But use them at your own risk.
First, since this is *unsupported by Apple,* there's nowhere to go when there's trouble.
Second, you're risking a future update preventing it from working, and perhaps rendering your backups useless.

What is the recommended virus protection softwear for iMac 10.6 Snow Leopard ?

My iMac v 10.5 has had viruses more than once. I recently upgraded to v 10.6 Snow Leopard. I wanted to check what virus protection was recommended. Best Buy told me MacKeeper was the best one to use. After reading reviews I am hesitant to install it. Any opinions?

Read Klaus's User Tips and his reference to Thomas Reed's website on Safe Macs.
It is not likely you actually had viruses since there are no known viruses in the wild that infect Mac OS X machines.
DO NOT take the advice of Best Buy...MacKeeper is one of the worst of the worst and most users on here consider it to be malware. Once installed it is extremely difficult to remove.
Anti-virus software is not needed with Macs. Definitely avoid that from McAfee and Norton as they have been shown repeatedly to cause serious damage to the operating system.

Upgraded both computers in the household and found Lion is too disruptive to workflow. Do I turn in the new laptop for a pre-Lion rebuild to keep Snow Leopard, or do I return computer and get upgraded memory to improve performance of existing MacBookPro?

Upgraded both computers in the household and found Lion is too disruptive to workflow.
Do I turn in the new laptop for a pre-Lion rebuild to keep Snow Leopard, or do I return new computer and get upgraded memory to improve performance of existing MacBookPro? I'm mostly still happy with existing MacBookPro, but Aperture doesn't work, the computer can't handle it.
Other possibility is setting up virtual machine with Snow Leopard server software on new computer.
Any opinions on what would allow moving forward with the least hassle and best workflow continuity?

Lion or Snow Leopard for MacBook 3.1

Hi.
I just want a few opinions on whether its worth putting Lion on my MacBook and iMac.
I have two 2007 Macs, a MacBook 3.1 2.2Ghz 4Gb Ram with SSD and an iMac 7.1 2.4Ghz 4Gb Ram Core2Duo machines. I upgraded at the time to Snow Leopard from 10.5 and then kept them on that as they run CS5 fine for my needs. The company I work for has kept our Mac Pro's on 10.6 still as well so it's been kind of handy in that repect.
Recently I've been thinking I should maybe put Lion on so they are more up to date. I know they'll both run it (the iMac will even take ML) I'm just concerned about any speed impact this will have?
I know they're old machines, but they run Snow Leopard great and are not slow. Just want to gather opinions on whether I should or shouldn't put lion on from people that have run it on these machines?
Many thanks

Something to consider when upgrading to either Lion or Mountain Lion.
If the startup disk needs repairing or you need to restore OS X, that requires the built-in utilities in OS X Recovery
Apple does recommend a high speed broandband internet connection for that.
Lion requires 7GB of disk space, Mountain Lion 8GB.
4GB's of RAM would be sufficient for both.
Good user tips to read for both Lion and Mountain Lion ...

Restoring snow leopard server

Hi
I'm hoping for some advice as I'm newish to managing servers and not exactly an IT head (but it's my job!).
Running Snow Leopard Server (up to date version, 10.6.7) on a Mac Pro tower (few years old now - dual Intel 2.66 I think). It has two 1 TB drives that are set to mirror each other, and some other smaller hard drives just for LAN time machine backups from other office computers.
At some point over the weekend, the server had an issue which meant nobody could log in (the server didn't appear on the network at all), and I just got the coloured spinning wheel when I came to log in to the machine. Switched off the server and started up again -- but it just sticks at the grey screen with the circular lines. Resetting P-RAM and running Disk Utility from the install dvd doesn't change anything.
My back-up made with Carbon Copy Cloner won't boot up either (I also have a Time Machine back-up -- haven't tried that yet) -- but therefore I have all the files.
What is my best option?
I'm starting to think that I'm going to have to reformat the drive, and reinstall the server software. Then hopefully I'll be able to restore the Groups and wiki files without too many issues (any thoughts on this? -- I'm worried I may encounter lots of permissions trouble here).
Any better options?
I would be thankful for any opinions/advice.
Cheers

HT1338 Should I update OSX10.5.8 to Snow Leopard?

Should I update OSX 10.5.8 on MacBookPro to Snow Leopard or something else?
I use my laptop for a wide variety of business and personal uses.

Hello:
That is an individual decision. Opinions are worth what you pay for them (sometimes) and mine are free.
IMHO, running an old and unsupported version of OS X is a prescription for future problems.
I would, at a minimum, update to OS X 10.6. Then, if your system will support it, I would then go directly to OS X 10.8.

Programs very unstable with Snow Leopard

'Upgraded.' I have programs quit all the time particularly when attaching, opening, and saving files especially when new file are renamed (save as). Any ideas how to fix this? Apple removed my last post saying this is 'feedback, that is weird. So I changed the wording; I hope this passes muster. Same problem with both IMac and Macbook Pro.

Any ideas how to fix this?
Try resetting some of the hardware involved (PRAM~NVRAM). See this Apple KB for details, etc.:
http://support.apple.com/kb/HT1379
Can't hurt to try, and apparently this has helped others recently.
As well, have you done due diligence on the basics.... confirm sufficient free space on the HD; validate disk health via DiskFirst Aid, never install SL from downloaded torrents/betas, etc. Let Spotlight finish indexing; clear out old cache files and outdated/broken/duplicate fonts; find and delete related plists.
Be aware that laptops are typically resource constrained - processing video as an example can tax the hardware and software. If you have large demands you might want to consider a desktop system.
Also, the general approach at this time is to ask if you've checked for any problematic fonts (all languages) with Apple's Font Book (look in the Applications folder). Find and remove all duplicates also.
Start there to be sure all fonts that are in play come out with a clean bill of health.
Don't hesisate to perform wholesale deletion of old and/or little used fonts - be skeptical of anything that has come from Office 2008, including those related to an Equation Editor installation.
By all means be sure any 3rd party apps AND plug-ins are Snow Leopard compatible.
If issues continue, you may consider walking that portable (and your install DVD so they can verify it is not flaky as well) in to the nearest Apple store and asking for opinions from the staff.
Good luck in any case.

Latest iMac with snow leopard on external/partition

I have the latest iMac, but I want to access snow leopard.
What is the best way to do this? make a partition on the internal drive and try install? or install onto an external thunderbolt hard drive?
I have a snow leopard disk that shipped with my 2011 iMac, just before the same iMac shipped with Lion
Would it be best to use this dvd or use a 10.6 dmg I have and boot from an external HD?

The fact of the matter is that the Snow Leopard EULA does not prohibit its virtualization in Lion or Mt. Lion: period, end of sentence!
If never fails to amaze me why people with no credentials in this area go out of their way to give incorrect "opinions" that deter people from running their PowerPC software in the Lion/Mt. Lion era.
Why not just take the high road and not raise the barrier to the OP of virtualizing Snow Leopard in the first place: something like discretion being the greater part of valor?!
There is no "unless and until..." standard that applies here; even if you would like to needlessly and irrelevently impose it.
The moderators on this forum do not like EULA debates (and for good reason, this is a technical forum), but:
If the issue is, for some reason, that important to you, over on the Parallels Support forum, a gentleman from the United Kingdom posted a detailed and lengthly argument to support his belief that the Snow Leopard EULA did prohibit virtualization. You can find my response there...

Snow leopard or lion for MacBook 2.1?

I want to do an OS upgrade to my mid 2007 MacBook currently running OS10.5.8. What is more appropriate, Snow Leopard or Lion? The only hardware upgrade I plan to do is RAM to 4 GB (3.3 available). Because of cost I don't want to upgrade to a SSD.
My question is will Lion run too slowly on my comuter with 4 GB RAM and no SSD (see specs below)? My current use for the MacBook are browsing, MS Office and similar, and streaming TV shows. I am considering Lion over SL because I read you can install the same aps as I put on my iPad Mini and iPhone 5.
Thanks for your opinions.

Is your MS Office 2004 or 2008. 2004 will not run under Lion because it's a Power PC program. Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.
