Mavericks or yosemite

Time to upgrade OS from Snow Leopard. Looking for opinions on weather to move up to Mavericks or Yosemite. Thank you, Andy
iMac, Mac OS X (10.6.8), 2.66 GHz intel Core 2 Duo, 4GB CS4

In my personal opinion, Mavericks is far more stable, perhaps due to being more time in the market. Some people have reported lose of performance on their computer (specially if they are slightly "aged") after upgrading to Yosemite. In all fairness, there are also a good number of cases that have made this transitions seamlessly. Whatever you decide you should remember that some apps may stop working in Yosemite or even Mavericks, before upgrading investigate if all your necessary apps have their equivalent in both operative systems. In any case, you could upgrade to Mavericks first, then decide if you continue upgrading to Yosemite or wait.

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.

Try this:
clone your system and repair it with Disk Warrior instead
Or try a clean test system install on another drive
A must: SmcFanControl 2.2 - a mere 400 rpm extra to keep air cooling up
Try to run w/o externals. MyBook included.
Is that a 7200.11 1TB? they had a lot of issues.
Run AHT off your OEM DVD.
2008 had to have EFI and SMC updates to deal with freezes on wake from sleep, and like all models, high inrush current. Hopefully you have a UPS and is 1500VA unit.
When you do hard restart from power button, you almost certainly add more directory errors and to files requiring immediate attention to repair and rebuild the directory; and to scan and repair and delete cache and temp files and folders. A must. Invest in bootable backups SuperDuper along with Disk Warrior (or TechTool Pro 6, maybe Drive Genius 3 but I'd rate that #3).
TimeMachine has its own bad habits, especially with Green drives and some externals.
Try to rule out everything and then add back one at a time.
And it may just be time to replace the 8800, very common, a couple threads this week, and it is 3 yrs old. Might want ATI 5870 or 5770.

After yesterday upgrading from Mavericks to Yosemite I can no longer find in Mail the icon (looks like the Add To Contacts icon without the + mark) I used to press in order to obtain an e-mail address from my contact list. What procedure should I use now in order to quickly add an address to an e-mail that I wish to send?

Can't backup in time machine or upgrade to Maverick or Yosemite, can I still transfer via thunderbolt?

I have a macbook pro 17 inch, Mid 2010 OSX 10.8.5. I currently have no back up as both my previous seagate and now my Lacie external drives won't back it up with the time machine. I get a box stating an error occurred and it quits after about 10GBs. In addition, the laptop fails to install Maverick and Yosemite when I have attempted to install them. For work I have just got a 15 inch Macbook Pro Retina. I obviously need all the data and files from my old laptop, if I were to transfer all the programs etc, would it likely transfer the problem that stops my computer from backing up? or is it more likely a hard drive problem and won't affect the new laptop?
I have followed trouble shoot and looked at previous posts but haven't been able to find a solution. Also I have gone on disk utility and verified the disk and all is fine there, so I am unsure what the problem is.
Ideally I can get working on the new 15" soon but I don't want to transfer over any problems.
Thanks

"Error Disk too Slow" Macbook Pro 2011 - Maverick and Yosemite - The Great Grand Mystery Unfolds!!!

Hey everybody,
Logic Pro X user here, have a late 2011 Macbook Pro, upgraded to 16gb of ram, 2.8ghz intel core i7, running latest version of Mavericks and more recently on a separate partition I tried Yosemite with a clean install of only Logic Pro X.
I use Apogee Quartet as my audio interface, I have a OWC Mercury Elite Firewire 800 external drive that I record to, all LPX files are on my internal drive.
Before Mavericks I had 0 issues with this setup, no with just one sole drummer track, or one single audio or software track, I get the various disk too slow errors after a few seconds.
I have tried reinstalling LPX, I tried a clean partition with nothing but Logic Pro on it (both Mavericks and Yosemite).
I have reset my PRAM and used Apple Hardware diagnostics as well as memtest (i think it was called) and even reverted back to my old original RAM that came with the computer. All hardware tests passed, I have verified and repaired disks from disk utility as well as from the recovery partition.
I have worked with Apple a bit over the phone doing these things, I have also read just about every thread on this pervasive issue. And its ruining my experience as a user. I absolutely loved Logic on Mountain Lion, no issues whatsoever! I'm considering reverting back to it actually.
On a side note I also have a HDMI Tv connected through the thunderbolt display, and a self powered USB hub that I connect my wireless mouse, iPhone cable and WD MY passport drive (which I only use for Time Machine).
I'm basically at my wits end and open to anybodies suggestions, I even tried resting the SMC and several other things advised in these forums.
I'm Stil under Apple Care and wondering if going into them is my only hope left.
I find that garageband acts the same, but I have no other system issues! its so bizarre, performance on all other programs is totally fine, its only when I want to record that I get issues.
For the record I do have some 3rd party VTS (Arturia V collection, EZ drummer 2 and AMplitube) but when I did the clean partition they weren't there and I still had the disk to slow error, so I'm not convinced its because of those.
Also Since the partition I obviously have played with my storage but I still have 75 gas of space on the mavericks partition (out of 500gb ) and on Yosemite partition I have 125 gbs available and on my Firewire external drive I have about 150gb left on a 500gb drive, so I'm not convinced its a space issue either (especially since before Mavericks Mountain Lion seemed to work just fine.)
HELP! Please help...I'm so exhausted trying to fix this on my own, and admittedly I've run to the end of my own capacity and don't know where to go from here.
Thank you for any suggestions, sorry for the long post, and if I have left anything out please let me know, this is my first post.

And yes I did upgrade my apogee drivers to the recent ones they just released.

HT1229 With iphoto version 7.1.5 can I update to Mavericks or Yosemite without losing photos?

I have OS X 10.8.6 Snow Leopard and want to update to Mavericks or Yosemite, but I have heard that many have had problems with iphoto in doing so. I have a particularly old version of iphoto (2008) and do not want to lose my photos of which there are relatively few--about 80.
Does putting the photos on disk ahead of time get around the issue of saving them before doing any upgrade?

If you want to continue to use iPhoto after upgrading to Yosemite buy an upgrade to iPhoto 9.6, once you have installed Yosemite. Then run the iPhoto Library Upgrader. see: iPhoto '11: About the Library Upgrader
If you do not want to keep using iPhoto, since your library is not large, export your photos from iPhoto to a folder on your Desktop, before you upgrade:
Select all photos in iPhoto and use "File > Export".
Don't upgrade to a new system without making a full backup of your computer. You will need this backup, if you want to revert to your original system. Before upgrading from Snow Leopard to Yosemite check all your important applications and device drivers, if they are Intel versions or universal versions. The newer MacOS X versions since Lion do no longer support the Roseta environment, that is required to run Power PC apps. If you do not upgrade these older apps while still running Snowleopard, you may not be able to upgrade them at all. See this User Tip:
Classic, Rosetta, and 32/64 bit revisited.

Photo Booth flash not working in Maverick or Yosemite

I have noticed that the photo booth flash in Maverick on my Macbook Pro and in Yosemite on my iMac is not working Screen flash is enabled on both.
So this is happening on two different computers. Does anyone know how to fix this? All my photos are so dark on both of my computers using Maverick and Macbook Pro.
It works fine on system 10.6.8 though.
Has anyone else had this problem too?
Martha

In case anyone is interested in your screen flash not working in the Yosemite or Maverick photo booth application, I finally called Apple today and he kept insisting it was working on his - I asked him to take a pic with the screen flash enabled and then disable it and he said it came out the same. And rationalized that it was because he was in a well lit room. I kept telling him in my old photo booth from system 10.6.8 that my face was lit up and my husband had reflections from his glasses so we went from him wanting me to reinstall my software (I refused since both computers were having the same problem - one using Yosemite and the other using Maverick) to him finally going into HIS partitioned disk that has system 10.6.8 on it to discover that the flash there reflected off HIS glasses too. Bottom line is he admitted there has to be some flaw that prevented the photo booth flash from working for Maverick and Yosemite. Whew, finally validation!

Upgrade external HD from Mavericks to Yosemite

Hi,
On my MBP I have installed Mavericks 10.9.5.
Then I have a couple of external hard drive with a clone of Mavericks 10.9.5.
If I have a cloned hard drive plugged in (not booting off from it), and I run the installer of Yosemite and I tell to install Yosetime on the external hard drive (where there’s a clone of Mavericks 10.9.5) what would then happen.
Would Yosemite erase everything from the clone, or would the clone upgrade from Mavericks to Yosemite, else?
Thanks

No, the Yosemite install will not erase everything on the clone.
Yes, the clone would upgrade from Mavericks to Yosemite. All your apps and data will not be touched.
I actually did something similar onto an SD card. I installed Yosemite 10.10, apps and data. Then later, I ran the 10.10.1 installer against the SD card and all that happened was Yosemite updated from 10.10 to 10.10.1. Nothing else was touched.

What is the best solution for migrating from Maverick to Yosemite?

What is the best solution for migrating from Maverick to Yosemite? Anyone have suggestions?

Back up all data. Update all third-party software to the latest version and remove any you don't need. Download the Yosemite installer from the App Store. Run it.

Firefox 33.1.1 running on either Mavericks and Yosemite crashes (infinite beachball) about a minute after opening. On both systems I had installed the XMarks and LastPass add-ons. I noticed that when I disabled those add-ons, the crashing behavior stopped. Is there a known issue with those add-ons and the 33.1 version of Firefox?

Does this also happen in Firefox beta? It is working for Yosemite for me on Beta channel.

If you have an external drive with an OS X Time Machine backup, then do restore of your last backup. If you have an external drive with a bootable clone of your previous system, you can boot to that clone and re-clone the OS X on your external drive back to your Mac's internal drive.
If you do not have either of these available, then the reverting/restoring process becomes much more complicated and involves purchasing an external drive and backing up your current system to that drive, then erasing, reformatting your hard drive and now your only options to installng an OS X version is doing a clean install of OS X 10.6 Snow Leopard, then upgrading, again, to either OS X 10.7 Lion or 10.8 Mountain Lion. OS X 10.9 Mavericks is no longer available for download and Apple has not made OS X 10.9 Mavericks available in any other form to be able to redownload and install.
Maybe it would be better to explain in detail your issues with Yosemite to see if any of us here can help you with your difficulties.
I am not running or using Yosemite, so I cannot help you with your Yosemite issues,
There are others here who can help you with Yosemite.
Good Luck.

I have just upgraded from MAVERICKS to YOSEMITE. My ageing EPSON CX3600 will no longer work. APPLE support gave me advice which did not work. How do I progress short of buying a new printer?

I have just upgraded from MAVERICKS to YOSEMITE OS 10.10. I have 4GB of memory.
Since upgrading my ageing EPSON CX3600 will no longer print. I get the error message ;COMMUNICATION ERROR.
Apple support gave me advice which hasn't worked including deleting the printer via system preferences and rhen restoring it after rebooting the system
Any ideas please.

I am thinking about upgrading OS to Mavericks or Yosemite, but I do not know if my Adobe suites Elements 10 and Photoshop 10 are compatible. Adobe site does not contain this information anywhere.

I should be very grateful if someone can confirm definitively whether Photoshop Elements 10, and Premiere Elements 10 would run on Mac OS Mavericks and Yosemite, to which I am thinking of upgrading to? Thanks in advance

The suggested Roaring Apps Table is not helpful. It shows both my Adobe Apps as compatible with all the latest Apple OS, except Snow Leopard, which is actually the App I currently use them with!! So this is clearly not accurate. I still need help with definitive answer. Any Adobe Staff out there?

Mavericks or yosemite
