The OS X 10.11 El Capitan upgrade is available only at the Mac App Store, which means if you have versions Snow Leopard 10.6.7, Mavericks, Yosemite, Lion, and Mountain Lion, the Mac App Store already exists on your computer.

Jun 11, 2021 If upgrading from macOS Sierra or later, your Mac needs 35.5GB of available storage to upgrade. If upgrading from an earlier release, your Mac needs up to 44.5GB of available storage. To upgrade from OS X Mountain Lion, first upgrade to OS X El Capitan, then upgrade to macOS Big Sur. My laptop had Snow Leopard 10.6.5, but the ‘Mountain Lion’ Installer I wanted to use needed 10.6.8 so I ran Software Update’ and it upgraded to 10.6.8 first. Download the Installer for the new version that you want. Update Os X Mountain Lion To Mavericks To confirm compatibility before downloading, check the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan or Yosemite. You can also find compatibility information on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini or Mac Pro.

This is a series of tips that cover Mac OS X client edition. Server forums cover Mac OS X server on the community.

Here is the series of tips for related Macs. 10.6,10.7, 10.8, 10.9, 10.10,10.11,

10.12 ,10.13, 10.14 Mojave, 10.15 Catalina , 11.0 Big Sur.


See special note about resetting the SMC during updates and upgrades, later in the tip.


September 13, 2021, an updated Safari 14.1.2 was pushed via Apple menu -> About This Mac -> Software Update.


is an article I wrote that everyone updating their Mac should read. No update should be ventured into with operating systems or software without first ensuring your data is backed up in two separate places. Slowing down of your Mac should not lead you to assume an update will fix everything. First isolate why your Mac is slowing down or crashing before installing anything new.

Apple includes many full upgrade installer links on https://support.apple.com/en-us/HT211683


Go to Apple menu -> System Preferences -> Date and Time and select the closest time server to set your time, and do so. Download based on manual time may fail, especially on older systems where the system time is not set right.


Be forewarned, Macs with solid state drives will be updated in formatting to APFS with 10.13 or later (this is discussed later in the tip, but bears repeating). This means if you need to downgrade the machine, you will need to erase the partition with the older HFS extended GUID to use the older systems. Regardless of which direction you go, backup your data first. This is only for Macs older than September 25, 2017.

Update Mountain Lion To Catalina Mountain


Apple released for 10.14.6 users, 2020-003 Mojave security update. If running an earlier version of 10.14, run the 10.14.6 Combo update first.

All of the Macs that are older than 10.11, need to be updated to 10.11 first before installing Mojave.

The oldest MacBook Air, Mac mini, and iMac which can upgrade to Mojave shipped with 10.8, Mountain Lion.

The oldest MacBook Pro which can upgrade to Mojave shipped with 10.7, Lion.

The oldest MacBook had Mac OS X 10.10 installed.

The oldest Mac Pro on the list above with the compatible graphics cards, had 10.6 originally installed, and is the only Mac that shipped with 10.6 that can install Mojave. Before upgrading to 10.7 or later, read this tip as Apple has not reintroduced a series of software that made older Mac compatible software compatible with Intel Macs since 10.6.8's release.


Apple released Mojave on September 24, 2018. Reports from:


earlier than that date were made with pre-release Mojave versions and can not be relied upon.


September 30, 2018 driver additions from third party update pages:

HP, and Samsung (HP has become the download site for at least some Mojave Samsung printers, if you have Samsung see if any are Catalina compatible)

Update Mountain Lion To Catalina Bay

10.14.3 was released January 22, 2019. Note, some users are reporting 10.14.3 will not successfully apply as an update without an SMC reset as described how to do in this link: https://support.apple.com/en-us/HT201295

Frequently both updates and upgrades will require multiple reboots to successfully apply. Do NOT become impatient if you find the screen go blank during the update or upgrade process. If you press the power button to shut it down while it is rebooting for the update or upgrade, it may quit the process, and leave you stuck.


Use the macOS Mojave forum for operating system specific questions of other end users such as yourself.

Note: https://support.apple.com/guide/disk-utility/partition-a-physical-disk-dskutl14027/mac

are directions for creating a separate partition that will allow you to dual boot into an older operating system

if you find something not compatible with the current. Once you install the older operating system, you can use the Startup manager to dual boot to the older system.


You can't install Mojave from the Finder, unless you are running 10.13.6 or earlier.


The direct download link for Mojave is:

Note: some people have had trouble downloading the latest Mojave links. https://brave.com/ has been found to be a better web browser than some if you run into issues and is known to work on Mac OS X 10.10 and later.


The SD card reader in the MacBook Pro 13' early 2015 no longer reads directly in the Finder under Mojave with a card formatted under a Panasonic FZ80. I found I could use the application Image Capture to read the card. What happens in the Finder, is instead of a generic floppy disk icon, I get a generic document icon. At least Image Capture is a work around.


Note: the 2020-004 security update for Mojave has a bug with the screen saver getting stuck. To repair delays in the screen saver, 'The workaround is to choose a non-picture screen saver such as Flurry, Message, etc.' (special thanks to community member dialabrain for this report.




How many versions of macOS are typically supported for each app?

Each major update will always support the current and previous versions of macOS. If you need to download a version of Coda or Transmit for use on older versions of macOS please consult the compatibility table below.

While we'd like to be able to provide support for even older versions of macOS, this isn't always feasible and can in some cases prevent us from being able to take advantage of the latest improvements in the operating system.

Update From Mountain Lion To Catalina

A note about Transmit 4's compatibility with Catalina and Big Sur

Unfortunately, Transmit 4 was discontinued nearly two years before macOS Catalina (10.15) was released, and is incompatible with any version of macOS newer than macOS Sierra (10.12.5). If you choose to run Transmit 4 on an OS newer than Sierra, it will launch and work in a basic form, but you may notice some instability in the form of crashes, exception errors, or hangs.

Update Mountain Lion To Catalina Island

Since Transmit 4 was discontinued, it will not be receiving an update to correct these issues. Inevitably, all software generally meets a similar fate. Once an app is discontinued and is no longer receiving updates, some future macOS update will cause the app to stop working eventually. Transmit 4 had a nice, long, seven year run but it was time to lay it to rest in favor of developing the next evolution, Transmit 5.

Mountain Lion Tracks

If you find that Transmit 4 is incompatible with your OS, the best option would be to switch to a different FTP client, be it one of the many free ones out there, or optionally upgrading to Transmit 5. Transmit 5 was released in July of 2017. Versions 5.6.0 and newer are fully compatible with modern versions of macOS.
