The classic OS X 10.12, or rather macOS upgrade, introduced tons of features anyone would still want on their Mac. Why? Because, it's well-tested and secure. Now we'll take a quick look at the legendary macOS Sierra upgrade. (In case you want to upgrade your Mac to macOS 10.13 High Sierra, check out this guide.)

Version 10.10: 'Yosemite' OS X Yosemite was released to the general public on October 16, 2014, as a free update through the Mac App Store worldwide. It featured a major overhaul of user interface, replaced skeuomorphism with flat graphic design and blurred translucency effects, following the aesthetic introduced with iOS 7. Below you can find an overview of the current Mac OS X 10.10 Yosemite compatibility status for our products. The applications listed as not officially compatible may work using the ' Steinberg Application Installer Tool '. As a prerequisite make sure to always have the latest eLicenser Control Center installed prior to the application.

OS X 10.10 (Download Yosemite DMG) OS X 10.11 (El Capitan) MacOS 10.12 (Sierra) MacOS 10.13 (High Sierra) Features of Download Yosemite DMG. The windows in this Mac OS update has a green ‘Zoom’ button to enter the full-screen of the windows. So you can enter full-screen instead of enlarging the windows size with this feature. If you already have macOS 10.12 Sierra, OS X 10.11 El Capitan, or OS X 10.10 Yosemite on your X220 we recommend a clean installation of macOS 10.13 High Sierra, not an update from the existing installation. See the guide here to install macOS 10.12 Sierra on the ThinkPad X220.

Interestingly, it first brought Siri to your Mac. This is great news for everyone who’s already used to her help on iOS. Then, there’s Watch unlocking for Mac, there’s one-click Apple Pay, tabs in apps, and cross-device copypasting. Just to name a few.

So, if you were on the fence about upgrading to Sierra, and in fact, any newer OS, go right ahead. Your Mac deserves a refreshment.

How to upgrade macOS: Sierra 10.12 compatibility list

As with the previous versions, macOS Sierra is available for a limited list of Mac models.
Here are the models of Macs that are compatible with macOS 10.12 and can upgrade to Sierra:

Does order matter when you upgrade macOS?

If your current operating system is OS X Lion (10.7), you can skip a few versions, and upgrade directly to macOS High Sierra. To upgrade to Sierra from, say, Mavericks, you’ll have to consequently upgrade to Yosemite and then to El Capitan first.

Check Your macOS for Sierra Compatibility

These OS versions can upgrade to Sierra:

• OS X Mountain Lion v10.8 or Lion
• OS X Mavericks v10.9
• OS X Yosemite v10.10
• OS X El Capitan v10.11

Here’s how to find out which OS version you’re running now:

1. Click Apple icon in the top left corner.
2. Choose About this Mac.
3. There you have it, in capital letters.

Memory (RAM): 2 GB (preferably 4 GB)
Sierra is pretty lightweight, so you only need 2 GB of RAM to upgrade. Cool, eh?

Disk space: 8 GB of free space on drive.
In the same About this Mac menu select 'Storage' tab. In front of the multi-colored bar, you will see the phrase, 'X.XX GB free out of XX.XX GB.' If you don't have at least 8 GB of free space, you should delete some old files.

Before you update macOS, don’t forget to:

Clean up your Mac

This is essential if you want a fast and effortless update, and glitchless work of your new macOS. And it’s also pretty easy. To give your Mac a cleanup, you need to get rid of system junk, uninstall extra apps, and clean some old caches. If that sounds like a lot of work, you can get a Mac cleaner like CleanMyMac for the job.

How to update your Mac: Clean it up first

1. Launch it.
2. Hit Scan to find all the extra files you can delete.
3. Press Run.

As you can see, I have 8.56 GB worth of caches, obsolete language files, broken downloads. You'll feel great getting rid of them.
That will give your Mac a basic system cleanup, but CleanMyMac is going to come in handy after the update as well. It monitors your Mac’s health, helps you speed up the system and remove unnecessary apps (Trashing doesn’t fully uninstall apps, by the way).

Back up your Mac

This is basic common sense before any Mac software update you’d like to undertake. Why? Well, because sometimes updates happen less smoothly than you’d like them to. To make sure you have all your information and files saved up neatly, you need a backup. To back up your Mac, you need to activate Time Machine.

• Open your Applications folder.
• Choose Time Machine.
• 'Select Backup Disk…'
  Note: You may need to first choose to 'Set Up Time Machine.'
• Choose where you'd like to store your backup.
• Both an external drive or an Airport Time Capsule fit.

• Switch the toggle on the left, from 'OFF' to 'ON.' Right beneath the name of your storage device, you'll see 'Oldest backup,' 'Latest backup,' and 'Next backup' — Your backup will begin within 5 minutes. To speed it up, click the arrow clock icon next to the Date & Time at the top-right of the menu bar and select 'Back Up Now.'

How to download macOS Sierra (or newer macOS) and install it

macOS Sierra is increasingly becoming a relic. Since 2020, the newest available macOS version is Big Sur. But it all comes down to hardware. Your Mac can only upgrade to the latest version its hardware can support. If your Mac is from around 2012 it can update as high up as to macOS Catalina. If your Mac is from 2010 or older, its limit is macOS High Sierra.

To download any new macOS and install it you’ll need to do the next:
1. Open System Preferences.. in the  Apple menu.
2. Click on Software Updates.
On top of the list you'll see the latest macOS version your Mac can download. In our case, it's macOS Big Sur.

Another way to do it is via the Mac App Store.

1. Open App Store.
2. Click the Updates tab.
3. You’ll see macOS updates available for your Mac.
4. Click Update.

Wait for macOS download and installation. Your Mac will restart when it’s done.

Now you have a new OS.
For historic interest, this is how macOS Sierra looked back then when it was still available in the Mac App Store. Now, it can't be found there anymore.

Download macOS installers directly from Apple

For users of past operating systems Apple created a handy a list of macOS installers. They go as far back as to macOS Yosemite. The first 3 of them will open and start the update process automatically.

• macOS High Sierra 10.13
  The 3 following installers will download macOS as a disk image (.dmg) After you unpack it, the macOS updater app will appear in your Applications.

We hope this guide has been of use, and don’t forget to clean up your Mac and back it up before you get the classic macOS! Cheers.

Well, I decided it was time to get ready for the latest Apple MAC OS 10.10. I’ve been running a variety of Apple operating systems since I first got my Macbook Pro in 2008. Of course, that system is still working great, but won’t be able to upgrade from the current version: 10.9 (OSX Mavericks). So that machines can’t be updated this time around, but my Macbook Air can. So my preparation begins.
My current Macbook Air has a 256GB SSD hard drive. It’s not the largest that will fit in this machine yet I don’t want to open it up to replace a HD. My issue is that it is full. I need space! Once I’m done calculating my drive space: music, photos, videos, work documents, songs, etc I am out of room. I literally get the System Full message weekly. Not good for my system either. So it’s time to DELETE.

As I prepare for OS X Yosemite, I realize I will need to clear out about 10GB of space. That is conservative because previous upgrades were slightly larger. It isn’t as easy as hitting delete either, so I will begin today to make room for the new features, bells & whistles I must not be able to live without. Here’s some quick things that helped me. Hope they help those too in a precarious situation: keep or delete.

DEVELOPER FOLDER
First, I begin with a look at the folders I have on my system. This time around, I realized that I had the DEVELOPER folder for Xcode still installed. No longer needing it, I deleted it right away. Net result: 1.3GB

iTUNES
Next, I ran one of my favorite tools: Gemini. It scans your HD looking for duplicated. Low and behold, I found some bible teaching albums in iTunes that I also had backed up on my drive. Went into iTunes and deleted the folders individually. Result: 3GB

Note: if you add an album from another folder, it will become a duplicate files as iTunes contains the new tracks. You can also safely delete the original tracks as well once iTunes adds them.

BACKUPS
Another tool I use to visualize my drive is OmniDiskSweeper. I used to use a more visual tool, but this seems to give me the best access to these larger files and folders. You can find it in the App Store.

I only recently realized that a complete backup of your i-devices can be really large folders. I mean really large. Deleting my iPad backup and I gain 8GB. Tempting…

If you use cloud-backups such as Dropbox or OneDrive, you may think you’ve moved folders or files from your computer to the cloud but often times you will have them on your HD plus in the cloud. You’ll have to stop the sync between them and remove the folder from your computer to lose the duplicate nature of those folders. Use with caution. My gain was 500MB

Do I need to keep deleting? Perhaps I will have to clean up my computer even further than I have today. One tool I love is CleanMyMac 2.0 – definitely worth the investment. It finds all sorts of goodies like language files (Russian, Arabic, Spanish, etc) that I don’t need – so hit scan and clean and they are gone. This didn’t help me this time around

Finally, you can use ONYX for a squeaky clean setup prior to the upgrade. This eliminates caches, history folders, user preferences and all sorts of system clutter. Use with caution as you can easily be overly aggressive with this tool. The other tool they make is called Maintenance and is highly recommended as well. This would be a finishing touch before you hit UPDATE.

YOSEMITE REQUIREMENTS:

As of this post, there are no official space requirements posted by Apple for the final release version of Yosemite OSX. If you’ve upgraded your OSX before through the App Store, you may remember the space needed for Mavericks was close to 11-13GB. The clean install of Mavericks was 11GB. The previous version required 16GB. So we are hopeful this one will be below 10 but I won’t hold my breath.

Comparison: If you are a Windows user, version 7 required 20GB and Windows 8 increased to approx. 24GB. So be grateful your requirements with a Mac is only 10ish GBs.

Compatible Macs able to upgrade to Yosemite:

• iMac (Mid-2007 or later)
• MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
• MacBook Pro / MBP (13-inch, Mid-2009 or later), (15-inch, Mid/Late 2007 or later), (17-inch, Late 2007 or later)
• MacBook Air / MBA (Late 2008 or later)
• Mac Mini (Early 2009 or later)
• Mac Pro (Early 2008 or later)
• Xserve (Early 2009)

Basic Yosemite Requirements:
Mac needs at least 2GB of RAM, 8GB of available storage and at least OS X 10.6.8 already installed. Serial uttaran me titra shqip.

CONCLUSION:
If you’re really lazy, you could dump nonessential folders onto an external HD and then move them back when your upgrade is complete.

Important: Perform a Time Machine backup once your machine is clean. Then and only then proceed to upgrading your OS X.

Always be cautious deleting & cleaning up your machine. And good luck with the OS X (10.10) Yosemite upgrade!

UPDATE: The new Yosemite is really slick. It took me about 20 minutes to update my 2011 & 2008 machine. Yes, my old late 2008 Macbook Pro was available for the update for free. AWESOME.

Os X Yosemite 10.13.6

What I noticed when I went to download was the warning tell me what the actual space requirements were for Yosemite. Drum Roll….

Os X Yosemite Update To 10.13 Free

Just 4.81 GB required for this upgrade. Loving Apple today. Very slick guys. Loving Yosemite and all it has to offer. At some point I will see what the actual effect of the upgrade was on space but for now, it’s great. Loving the integration and once iOS 8.1 is released, complete tie-in features will be available.
