Q: How do I go from Mavericks back to Snow Leopard
-
Mar 21, 2014 9:05 AMby MichelPM,Hello Tara,
Not addressing your Time Machine inquiry, but I believe you need to know some things about your upgrade to Mavericks, so you have a better understanding of what is going on and how we here can help you.
FIrst, you were on OS X 10.6.8 Snow Leopard. That is 3 OS X releases from Mavericks. Many things in OS X have changed since then.
No matter when you decide to upgrade to a later Mavericks version, chances are if your Mac is having issues with it now, it is still going to have issues later down the road.
Things that can slow performance on a new OS:
Not enough or barely enough installed RAM.
Not enough hard drive free space.
Running antivirus software on your Mac.
Running "garbageware" like MacKeeper, CleanMyMac, TuneUpMyMac and the like.
Not having up to date, OS X Mavericks compatible software.
Having old, outdated, incompatible software installed.
If you have any connected third party non-Apple peripheral devices, these need update software and device drivers found on the device makers' websites'
If none if this is addressed, everytime you attempt an OS X upgrade from here forward, you are going to keep experincing issues.
If you would like help to sort out your Mavericks issues, It would help us to help you if we could have some more technical info about your iMac.
If you so choose, Please download, install and run Etrecheck.
Etrecheck was developed as a simple Mac diagnostic reporting tool by a regular Apple Support forum user and technical support contributor named Etresoft.
Etrecheck is a small, unobstrusive app that compiles a static snapshot of your entire Mac hardware system and installed software.
This is a free app that has been honestly created to provided help in diagnosing issues with Macs running the new OS X 10.9 Mavericks.
It is not malware and can be safely downloaded and installed onto your Mac.

Copy/paste and post its report here in another reply thread so that we have a complete profile of your Mac's hardware and installed software so we can all help with your Mac performance issues.
This is up to you.
Good Luck on whatever you decide.

Mar 22, 2014 5:16 AMby Tara Hollander,Thanks for the links, Erick Root. I had read the first article "Revert to a Previous OS X" and may have come across the other articles, but not read them, which is why I wanted to post my own inquiry on the discussions. There are very different instructions and so many extra steps in the second posts
Revert to former OS from Mavericks
compared to what Apple says.
I'm still not clear on the answer to what I should do. The last article for revert to Snow Leopard states, "With all other drives disconnected your ready to erase 10.7/10.8 completely off your boot drive, and you do need to erase the ENTIRE drive....Do not select the indented names, those are just partitions on the drive, you need to erase the entire drive to catch hidden 10.7/10.8 partitions and rebuild the partition map back to 10.6 version."
Which is it, can I follow Apple's instructions and
- Choose Apple menu > Restart. Once your Mac restarts (and the gray screen appears), hold down the Command (⌘) and R keys.
- Select “Restore from a Time Machine Backup,” then click Continue.
Or is the later article post the case and that I have to lose my partitions? That second 100gb partition that continues to run Snow Leopard has been a life saver for the last 3 days, because it actually runs the way my computer should and has been running - fast! I would like to keep that partition. It is a stable, not extra applications, test partition. Can I keep it and follow Apple's instructions, "Restore from a Time Machine Backup" or will I have problems?
Please confirm why one way may be better than the other and the consequences of either.
Thanks!

Mar 22, 2014 5:35 AMby Tara Hollander,Thanks for the post MichaelPM. It is more than I want to consider because of the time commitment, but I have always been aware of the possibility of old programs, or files perhaps corrupting or causing problems and that this could continue into new OS upgrades. I may or may not have time to address and tackle the issues you suggest, but I would like to give you information so that the community can perhaps suggestion answers of what is truly "must do" actions no matter which way I go. If good sound suggestions are provided, I will follow them, as I am a person who generally understand a lot of details about the Mac (intermediate-advanced understanding), but is not super advanced.
1. I have 4GB of RAM and that has worked very well. (I also thought and was enticed that Mavericks was supposed to have engineering updates that made the OS more efficient in terms of CPU use, etc., etc. - so wouldn't my 4GB of memory be sufficient?)
2. I have more than 85% of my HD free of space, which I understand is considered good practice. Details are I have 397GB capactiy and 101.4GB available.
3. I do not run antivirus software.
4. I do not run the cleaning softwares you mentioned. (I have OnyX, but haven't used in in over 14 months.)
5. My only software that was PowerPC was Quicken 2006, which I deleted from the Applications folder (but not any files, extensions or preferences from other folders - where are they?), and Epson Scan.app, which I also deleted/moved to the trash.
6. I have not yet connected my LACIE backup hard which has my time machine backup with OS 10.6.8 files, so I don't think that can be an issue (i.e. it is not trying to index the backup as I understand other people have problem with constantly happening and making the computer run slowly.
So I feel these things are addressed unless you can explain otherwise. Please advise.
I would like suggestions and response to this post, but in another post I will copy an entrecheck report.
Thanks!

One other issue that concerns me. I launched Activity Monitor because the computer was so slow and it shows the "memory used: 3.99GB" out of "Physical Memory: 4:00GB" seems like it is being used up (though Entrcheck may be giving different information), which doesn't make sense as I wasn't running too many, and not energy/memory hogging programs (i.e. just Mail, Contact, Safari, & OverDrive).
Any thoughts on this?

Mar 22, 2014 7:53 AMby Eric Root,HelpfulYour choice(s) depend on how your hard drive is partitioned. If your 100 GB partition is the first/top partition, you can delete the Mavericks partition and expand the top partition down. If your 100 GB partition is the second partition, then you will have to erase the hard drive to recover the space. Try Apple's suggestion first as it is the easiest.
If you will open Applications/Utilities/Disk Utility, select the Partition tab, and take a screen shot, perhaps someone can make a better suggestion.
You might want to decide if you want to solve Mavericks or revert so people trying to help can focus on one or the other. Mavericks runs fine on the 2 computers in this house and in some areas is faster than the Snow Leopard partition I have.

Mar 22, 2014 2:33 PMby Tara Hollander,Thanks again for the reply. Unfortunately, the 100 GB partition is the 2nd partition. If I try Apple's suggestion first, will I have 100 GB of unusable hard drive space? Or, will that process automatically erase both partitions and give me one 500 GB hard drive?
I would like to revert to Snow Leopard (maybe tomorrow), AND, continue to fine tune my system and files to be better prepared for a more successful upgrade of the OS in the near future? Thus if people are able to give feedback on my etrecheck report too (below in this thread), please do and thanks!

Mar 22, 2014 3:43 PMby MichelPM,HI Tara,
Sorry, I have to get back to you so late, I have been away today.
If you are using any Google software, especially, Google Chrome or Drive and, maybe even Google Earth, it is best to uninstall all of this software per instructions on Google's website.
Currently, Google software has some capatibility problems with OS X Mavericks.
In additon check to see if there is updates for all of your installed software.
Not all Mac software is listed at the Mac App Store. So, you will need to visit some software developer's website's to check for updates.
One piece of software to immediately check for updates is Telestream Flip4Mac.
If there is no Mavericks compatible updates for this Internet plugin, then unistall this per instructions on the Telestream website.
Download, install and use VLC playerr, instead.

Mar 22, 2014 3:51 PMby MichelPM,Also,
Mavericks uses memory different from previous versions of OS X.
Mavericks will tend to make use of all of the available memory installed as needed.
That stated, your MBP can take a total of 8 GBs of RAM.
I would strongly advise purchasing and installing the additonal 4 GBs of RAM into,your MBP.
Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
Good Luck!

Mar 23, 2014 7:21 AMby Tara Hollander,Thanks for the post, much appreciated.
I will follow these suggestions on uninstalling Google software and one-by-one check software updates for other applications.
Question: Can installed software that's on the HD and not the most updated version, but not being used, cause problems or slow down a computer?
Thus, if I uninstall these programs, and update ones needing updating, will Mavericks and my computer run more normally and faster and not be super slow?
Thanks.
-
Mar 23, 2014 7:24 AMby Tara Hollander,Since I hadn't had a slow MBP until upgrading to Mavericks, I didn't think upgrading memory was needed on this MBP, though I've done it regularly with previous computers (PowerBook G4, PowerBook G3, and desktop Macs).
As I posted in another thread only about my memory situation, I received within a reply the following:
"Adding RAM only makes it possible to run more programs concurrently."
I utilized running multiple programs at once always, and switching between them regularly so I will upgrade to the full 8 GB of memory to maximize that computing method.
Ordered from OWC as I've worked with them in the past.

Mar 23, 2014 7:32 AMby Kate_Mac,Tara, I'm sorry you're having these problems.
This would be a good time for you to learn procedures that will keep you safe and happy in the future any time you are considering installing new system software. I too was considering upgrading from Snow Leopoard to Mavericks, here's what I did....
I installed Mavericks on an external hard drive, not the hard drive I normally use. Then I installed the latest versions of the main apps that I most often use on to the drive with Mavericks. Then I tested some of the things I normally do with those apps.
The point here is that I didn't touch my main hard drive with my current Snow Leopard set up in any way.
Thus, when I concluded that Mavericks wasn't for me, I didn't have to fix or change anything. I just rebooted my main drive, and returned to work under Snow Leopard.
I'm sorry this post doesn't really help where you are now, but in the future you will face many more opportunities to install new system software, so I hope I've helped you avoid many potential problems down the road.
-
Mar 23, 2014 7:49 AMby Tara Hollander,Thanks, this is helpful, and I will consider this practice in the future. I thought I was pretty secure having the second partition with Snow Leopard still on it, and in fact, I think it was/is a good thing, but I see the limitations now of that partitioning and the benefits of always having extra backup external drives. I have one only (to go with this computer) and keep it with only TM backups.
BTW, Can I install Mavericks on a 500GB Lacie external HD, while it is the main storage location of my Time MAchine backups?
Also, people talk about creating a extra copy of Mavericks on a bootable USB or other
Can I install a bootable Mavericks installer on that same 500GB Lacie external HD, or does it need to be on it's own separate data storage such as a USB stick or thumb drive?
Of course a trial of the new OS on a separate drive keeps everything, well, separate, but also an external HD will always run a bit slower, at least it has been in my experience, than the actual drive on the computer, but it will allow me to work with and test the new OS.
Thank you very much for your post. I will utilize it in the future.
And the two above questions are fair game for anyone to help me as I will try to keep a copy of Mavericks even if I revert to Snow Leopard.
