Memory needed for Yosemite

RANDALL MILLER
I have seen on the web that at least one blogger has suggested that if you have less than 8 GB of memory you should not install Yosemite.
Is there anyone running it with less than that, especially 4 GB on a MacBookPro?

Re: Memory needed for Yosemite

If I remember correctly, the very original Mac only had 128K of memory. That’s unthinkable these days. Both OS and apps have grown considerably since then packed with features that most of us may not even need.

I have 8GB of memory in my Mac Mini and sometimes even that doesn’t seem enough. It may not be too long before 16GB becomes the minimum requirement.

Using and OLD minimum requirement MBP with 4GB and it runs fine. It's not blazing but it's not annoying.

I agree. I put 16GB in my 2009 Mac Pro. Working on a number of projects; 10 apps active including Finder. Activity Monitor shows

Physical Memory: 16.00 GB
Memory Used: 10.11 GB.

I installed Yosemite on an 2008 MBP with 6 GB RAM. It runs reasonably well.

I installed it on my really slow 11" 2010 Macbook Air (1.4Ghz Core Duo) with only 2GB of RAM and 64GB SSD. While I haven't done much with it yet, in my preliminary use it seemed about as sluggish as it was under Mavericks. Which is to say, not bad at all for my basic needs.

Of course, I pretty much only use the MBA for light (plain text) word processing and when I travel. Just booting the thing uses up the 2GB of RAM and starts hitting the scratch disk, but Mavericks/Yosemite's memory compression helps quite a bit. I don't really run more than one app at a time if I can help it, and when I do that it works just fine. Seems about the same under Yosemite.

I installed it on a 2007 20-inch iMac (about the oldest Mac you can install Yosemite on) with 4GB of RAM.  Previous to installing Yosemite, this iMac was running Snow Leopard and performance was great.  

I did a clean install (not an upgrade install) of Yosemite.  Afterwards things were noticeably zippier!

That said, I've been recommending that folks have 8GB of RAM for Yosemite also.  I think that in the long run you will be happier with that much RAM on board.

I should note that, with the clean install, that I'm not experiencing any of the Wi-Fi or Safari problems that others are experiencing.

I have not upgraded yet, but was planning on a clean install when I do. Thanks for the confirmation.

Good question but I don't know the answer.

I do a clean install to remove accumulated garbage such as apps I ended up not using and their associated system files. Also garbage from web site visits. So I only install my data files from back ups and I reinstall apps from scratch.

For example, I just bought a new MB Air and noticed the HD has about 210 GB of files on it whereas my Mini with the same files has 300 and runs slower despite having a faster CPU. It really did not take long to set up the Air with everything I needed.

I want to emphasize I make Two New Back-ups to fast external HDs before starting. One is a finder format back up of just my files and saved app installers and the other is a bootable clone.

But I have been doing it this way for 20+ years so have the necessary knowledge. I also never cared if I lost all old emails, bookmarks, etc. But internet services and IMAP email solve those problems anyway - thank you TidBITs.

Don’t think so…if you use Migration Assistant or restore from Time Machine…even if you only migrate your homedir…you’ll most likely drag some old stuff over. The only real way to do a “clean install” is to install everything from scratch and then only drag copy or TM restore your data files. In particular, you don’t want to just copy the contents of ~/Library back as there’s lots of potential stuff in there. There’s also stuff like Mail archive folders in there so you’ve got to know what to copy back.

Me…if there’s nothing wrong with the existing installation I just do an upgrade install. If I have to do a clean install from the nuke and pave on the drive then I just migrate my homedir back…and since I always install 3rd party system stuff for all users it goes into /Library or /System/Library instead of ~/Library. Apps and all that system enhancement stuff gets fresh installed if I go that far…but I rarely do that.

You’ve got to know what you’re doing even with a clean install as some apps (Photoshop, I’m looking at you) break unless you deauthorize them on the old install and reauthorize on the new install…although sometimes naming the computer and drive the same as the old install keeps them working.

Reinstalling everything of course…requires that you know all your serial numbers or that you bought everything through the App Store…so I keep all those in a FileMaker Pro database.
