To control how the latest macOS is installed, Apple has locked down ways to install it. With the dramatics out of the way, there are various ways to install macOS on your Mac, Apple provides many options. This quick guide is designed to answer questions you have and provide a bit of clarity on the different processes. This is based on our experience and is always being revised. If you can add to these guides, please contact us accordingly. If you don't have a Time Machine or a working mac drive with the latest macOS then you only have one option.
So if your drive or Time Machine was created with Sierra, then that is the macOS you can download and install. You can not install High Sierra or Mojave. The latest macOS is only available via an upgrade path. To use Time Machine restart your Mac while holding down the option key. Using your old drive to get a new macOS Your current hard drive will most likely have a recovery partition.
This should make the Mac boot from the recovery partition. If a spinning globe of the world appears, then it is going to Apple website to install an older version of MacOS, so cancel that operation or shut the Mac down via a hard power off hold down power button. You need to restart holding down the option key, select the recovery partition on the drive that appear. Hold down the option key and reboot the Mac. Holding down the option key loads the boot manager and the Time Machine drive should appear onscreen.
You will have the option of installing a new macOS there are also options to restore from Time Machine and Disk Utility. Your Mac is not seeing the Time Machine. Make sure there is a physical connection not wifi. Is the Time Machine turned on? All MacOS software is delivered digitally.
If you have original software media for an macOS like Snow Leopard you can install that software and then upgrade via the App Store to the current version. Use the current MacOS upgrade guide for more information.
You can buy from an Apple Store or calling Apple Support. If you have disconnected the battery, the date could have reset. Part of macOS Utilities is Terminal. It is found as an option in the top menu. Select Terminal. If you are connected to the internet then type: ntpdate -u time. If not, then use this manual method: date which is February 1st or 8pm So mmddhhmiyy all two digits. Either there is an old partition on Time Machine or on the Mac drive. Apple and most of the internet recommends this method, however it does not give you control over which partition the Mac recovers from.
Holding down the option key and restarting the Mac goes into boot manager, and you can see all the drives the Mac can boot from. Make sure you choose the right one! Hold down the Option key as your Mac starts up. The system should create the macOS Ulitilies page. We are still troubleshooting this, we will have a new section on EFI shortly. If it fails, there is no warning or notification. So there are a lot of Macs with outdated EFI. It may have been corrupted or tampered with during downloading".
This is a check Apple has introduced with system installation. They don't want old OS versions installed, better to move everyone to new OS, and new hardware buy a new mac. There is a simple work around. If you are in OS Utilities, the top menu should have a drop down that has Terminal. Run terminal and then type this in: For El Capitan install use: date [enter] You can check the date is now by typing: date [enter], it should now display: October 1st or 8pm The date after El Capitan's release. You can now install El Capitan without an error. Dates for other systems are: Yosemite: date Mavericks: date Apple includes an awesome app called Migration Assistant that we have used to help customers start over with a fresh macOS but keep all their data and applications.
Apple allows a lot of different installation and migration options. We will discuss the main ones here, but if this does not answer your migration question, please contact us for more specific information about the upgrade you are planning. What is Migration Assistant Migration Assistant allows you to transfer applications, settings and data from another Mac. A mac can boot from an external drive, for example, if you put your old hard drive into an external enclosure, you can boot from it, and run that hard drive and it would be exactly the same as your old mac If you just want a new macOS, start fresh with no legacy upgrade data, then you can use Migration Assistant to reinstall all your data and apps, and you will have the benefit of a new macOS with all the apps and data from your old drive.
How to use Migration Assistant After you have installed the new macOS, the system starts and asks for generic information: country, keyboard type etc. The next part of the installation setup is Migration Assistant. If you have installed a new SSD, you can use either your old hard drive in an external enclosure or a Time Machine back up as a source for Migration Assistant.
The example in the image below, a Time Machine disk is connected and to be used Select the machine you want to restore from in Time Machine Then select the type of data you want to migrate That is it! You should have a new macOS with all your applications and data restored back on the system. If you are migrating to an old version of OSX such as Lion, then you need to use another method. This method is not recommended if the macOS are too far apart in release. It is ok if you are moving from Sierra to High Sierra.
But if your computer is on Lion, your application and core system files will not be compatible with High Sierra or Mojave. We have renamed this section the good, the bad and the ugly. These are the undocumented or little known Time Machine features that can make your life easier or harder when upgrading to an SSD. If your Time Machine is backing up your whole drive, yes the macOS is backed up.
You have a complete back up of your Mac. You do not have to download macOS to use your Time Machine. It is not totally understood what is happening, but it is not uncommon for Time Machine to get additional files from the Apple website before restoring a Time Machine back up.
Usually these files are to do with the recovery partition on the Time Machine or the Disk Utilities page. In our tests, we have found Apple has separated out the OS and the data. The bad is for customers that have installed an older macOS, such as Lion, via internet recovery. Rebooting off Time Machine Time Machine does not have a recovery partition, however you can use it to restore your Mac or install a new macOS. This loads the boot manager and you can see all drives attached to the Mac.
The Time Machine should display as an external drive. Select it and the Mac will build a macOS Utilities page that will have Disk Utility to initialise a new drive or erase a current drive and install a new macOS. If you have a mechanical hard drive and have upgraded to High Sierra or Mojave, most of the time this drive is formatted as Extended Journal. It will name the SSD the same as the old hard drive even if it is preformated and named different and it will format the drive as the same as the one on the Time Machine, which is usually Extended Journal.
This is the problem.
Currently we have two work arounds. The easy one is clone the drive do not restore from Time Machine. Time Machine will restore the data but not overwrite the new OS. When you restore from Time Machine it restores everything including the disk name.
It is the disk name duplication that kills me every time. You erase your new SSD, give it a clever name like Ernie because your current hard drive is called Bert. What happened to Ernie? Ok, I know, you can go and rename the drive to Ernie but what if this is a second drive. Both drives are called Bert, how do you know which one is which? It is important, because you need to set the new SSD as the start disk in preferences. You can not rename the drive in disk utilities but you can change the name on your desktop. So go to the desktop, you will see two drives, both with the same name.
You can click twice on the name slowly and it will highlight so you can rename it. Then go to Disk Utilities see which drive you changed. That way you can work out which is the new SSD and which one should be renamed Ernie. We have recommended Diskmaker X in the past but the method we outline here is the recommended method from Apple. For High Sierra click here. If you have already downloaded and upgraded to Mojave or High Sierra you will need to download the MacOS you want again Apple deletes installer once it has been used. It does not have to be a super fast USB 3. It does not have to be a USB.
You can use an external hard drive note: any data on the drive will be lost as it gets formatted. You can erase and rename. The MacOS creation method will reformat the drive, so it does not need to be any specific format type like Fat32 or Mac Journaled. What is important is the name of the drive, as it is used in the code below.
We are going to use the command line app called Terminal to create the MacOS drive. Don't worry if you have never used it, it is very easy, not that scary.
Open Terminal, it is found in the Utilities folder in Applications. Paste the code you copied into Terminal and hit enter. It will ask for your system password usually the one you log on with at start up. Type Y and return when it asks if you want to erase this drive. When it is finished creating it will display "Copy complete". You can close Terminal.
Select and hit return. You do not need to select a network. Go into Disk Utility, Erase and name. Proceed to install macOS. Please note Apple have added a new format type in High Sierra and Mojave. When you get your new SSD it is uninitialised. This means it can be used in a Mac or PC. It needs to be initialised before use. In the PC world they call this formatting the drive.
In the Mac world it is called Erase and it is a function of Disk Utilities Disk Utility is a tool included in many places. It is found in the Utilities directory in Applications. It is included in any macOS install app. It is also a part of the Internet Recovery boot up. There are many reasons why you would want to erase a drive, this guide is focused on initialising a new SSD, however for readers who are looking at general information we have added the following warning Warning : Erasing a disk will delete all data on the disk.
I know that sounds obvious but you would be surprised with the support calls we get Four steps to initialise a new SSD. When you start Disk Utility, in the sidebar are the drives attached to the Mac. Select the disk name, not the indented volume name. There are two to three fields that need to be selected. Please note: this process cannot be used to clone a Windows partition created by Boot Camp. We recommend WinClone by Twocanoes Software. It is commercial software requiring a license to use, however it is not affiliated with our company and that is not an affiliate link.

Before cloning, the SSD needs to be initialised, if that has not been done, please follow our instructions above. The process is really only two steps When the download is complete, install in your Applications folder. Double click on the SuperDuper! Click Copy Now to begin. You will be notified when it is complete.
Is the SSD the same physical size as my current hard drive? Both the standard Apple Macbook and Macbook Pro hard drive are an industry standard 2. They are physically exactly the same physical size. Does the Macbook Pro use a standard M.
It is only standard in it's physical size. A standard M. Apple has made their drives proprietary. Are the 2. All our current SSDs are the same speed and quality. The GB is as fast as the 2TB. Do I need a bracket to install the SSD? Can I do this install myself? We have had customers of every type of experience: students to pensioners do this upgrade. It is only slightly more complicated than a RAM upgrade. Do I need any special tools? For the pre models you need a small phillips screwdriver and a Torx 6 screwdriver.
These are standard tools, found in many kits and available at hardware stores like Bunnings. Everything you need is in our screwdriver tool kit.
The Aura SSD kits include all the tools you require. Can I clone a bigger drive onto a smaller SSD? The cloning software we recommend does not selectively clone. It is all or nothing. Does the hard drive and the SSD have to be the same size? As long as the source current hard drive has less data than size of the new SSD. What size SSD should I buy? It all depends on your work flow and how much data you store and delete.
Can SuperDuper! We recommend Winclone for this type of clone. If you have read or downloaded this guide in the past, you might want to know what has changed, how have we updated this guide. May Brought back the old cloning method, it is now called the External Clone Method. The reason is a lot of customers like to use third party software to clone. January Fixed wording that sounded like we give you a free cloning cable. Cables must be bought separate. Reproduction without explicit permission is prohibited.
