Suggested April 2024 How To Install Os X 10.10 Yosemite Beta On A Separate Partition

When Yosemite was first announced with all of its awesome features, I exclaimed on iDB’s group chat session that I would be installing the OS as soon as it was available for download. Sebastien quickly rebuffed my excitement and told me how unreasonable it was to install a beta OS on my main machine, and especially so while I’m out of the country. After being a bit disappointed (that wasn’t what I wanted to hear at all…I mean, SMS texting on OS X!) I eventually came to the realization that he was right.

But then, I remembered that I didn’t need to settle. I could easily create a partition on my Mac and keep Yosemite completely separate from my main (and stable) Mavericks install. It had been a while since I had last messed around with disk partitioning in OS X, but it didn’t take long before I was installing the Yosemite beta on the same Mac where my primary Mavericks install lays its head down at night.

The benefits are multi-faceted. Number one, you get to try out Apple’s new OS right now. Number two, you don’t have to worry about buggy beta software cramping your style; after all, you’re still running your main OS on the a separate partition. Number three, it can be done quickly, and with little to no downsides (as long as you have the disk space to spare). Check inside for our full tutorial that shows you how to install OS X 10.10 Yosemite on a separate partition on your primary Mac.

Before starting

You also need to ensure you have adequate free disk space. If your primary OS X installation consumes most of the hard drive space, you’ll need to delete some files, or reconsider your options. If you actually want to be able to use and fully test your Yosemite install, I recommend at least allocating 50GB of storage space to Yosemite partition. You might be able to scoot by with 30GB~ but that’s really pushing it if you actually want to be able to use Yosemite, download updates, and download apps.

On my actual machine, I’ve allocated 50GB to the Yosemite partition for testing purposes. Only you will know what you truly need, but the more space you can allocate (within reason) the better.

Video Tutorial

If you’re not familiar with creating partitions and the exact procedures behind doing so, then I definitely recommend that you follow the step-by-step tutorial below. However, if you just need a brief refresher course, then this less than 2 minute video should be sufficient enough to get you started.

Please watch this video in full screen and choose high resolution settings. It has been recorded and exported in high resolution so that you can make out the details better on a computer monitor.

Step-By-Step Tutorial Download OS X

Step 1: Download OS X Yosemite via the Apple Developer Portal. Even if you’re not a developer, you can download it via Apple’s Yosemite OS X 10.10 public beta.

Step 2: Initiate the actual download via the Purchases tab on the Mac App Store app. The download is quite large (over 5 GB) so use patience when downloading.

Step 3: Once the download is completed, you should see a new “Install OS X 10.10 Developer” in your Applications folder and in Launchpad.

Partition your Hard Drive

Step 1: Launch Disk Utility, which is available in /Applications/Utilities/Disk chúng tôi You can also find the Disk Utility app by searching via Launchpad.

Step 2: On the Disk Utility app, you should see Macintosh HD in your list of items on the left-hand side of the app. You will likely see two ‘Macintosh HD’ options. The first one applies to the logical volume, and the second nested ‘Macintosh HD’ applies to the primary partition. Select the first ‘Macintosh HD’ option.

Step 5: Position the drag handle to ensure that the Macintosh HD 2 partition has enough space. I recommend using at least 50GB.

Step 6: Under Partition Information on the right-hand side of the screen, you’ll see the Name input box. By default the name will be Macintosh HD 2, but I recommend renaming the partition to something that’s easier to identify. Since we’re installing Yosemite, I suggest using the name Yosemite HD.

Step 8:  Creating the partition will take a few moments. After the partition is created, you will see another partition—Yosemite HD—listed under the Macintosh HD logical volume.

Install OS X 10.10 Yosemite on the new partition

Step 1: Launch the “Install OS X 10.10 Developer” to begin the Yosemite installation process.

Switching between operating systems

After the install completes, you’ll be booted into Yosemite. You can easily switch back to your older OS X install, presumably Mavericks, by rebooting and holding the Option key (⌥) as you reboot. You can also use the built in Startup Disk feature found in System Preferences to switch between OS installs.

How To Get Iphoto Working Again In The Os X Yosemite

With OS X Yosemite you have a new app called Photos that all iOS users might find familiar. The app works much the same way as iPhoto did, but it brings a new and improved user interface for its users.

After working around the issue, a solution has been found that lets you make the iPhoto app on your Mac work again. Here’s how you can apply the fix on your Mac.

Getting iPhoto Working Again in OS X Yosemite

Just to make sure that you are facing the exact issue that we have a solution for, you need to first launch the app and see the error message.

3. As soon as the Store opens you will see a message that says “Item Not Available.” This is the issue that you are going to be solving in the rest of this guide.

7. Once the app has been updated, launch it and it should work for you.

If that solves the issue for you, you do not need to follow the steps given below. In case the issue still persists, follow the below steps.

9. Select “Users & Groups.” You are going to be creating a new user account to install the iPhoto app in. Then when you come back to your original account the app will work.

When the new user dialog box appears, select “Administrator” from the “New Account” dropdown menu.

Select “Use separate password” in the “Password” section.

When the app is installed, log out from the new account, log back in to your regular account, and launch the iPhoto app.

If you are a big fan of iPhoto and do not want to switch to the Photos app, you can continue loving your favorite app as it still works just fine on your machine.


If you suddenly found out that the iPhoto app no longer works, and you had some really great albums in it, the method above should help you get it working again on your Mac.

How To Install The Ios Or Ipados 13 Beta

You’ve been warned.

Apple offers two ways of installing the betas.

Two ways to install iOS and iPadOS 13 beta

In the past, installing a major iOS beta was a simple matter of grabbing a special configuration profile for your device from Apple’s portal for developers that in turn prompted the Software Update mechanism to find and present an over-the-air beta update to the user.

With the iOS and iPadOS 13 beta, Apple has moved to different methods that involve using either the developer beta of macOS Catalina 10.15 or the Xcode 11 beta.

How to install iOS or iPadOS 13 beta using Xcode 11

This method is perfectly suitable for people who are currently running macOS Mojave or one of the earlier commercial releases of macOS because it doesn’t require updating their computer to the macOS Catalina 10.15 beta. What you’ll do instead is download and install the multi-gigabyte Xcode 11 beta which in turn will let you install the iOS 13 beta through iTunes.

1) Visit chúng tôi on your Mac and sign in with your Apple ID account.

The Xcode beta is a 7.66-gigabyte download so now could be the perfect time to do a little spring-cleaning and free up storage space on your Mac. For that, we recommend MacPaw’s excellent cruft-cleaning app, CleanMyMac, available as part of Setapp subscriptions.

3) Wait for the Xcode 11 beta to finish downloading, then launch the installer.

4) With the app successfully installed, open the Xcode 11 beta from your Applications folder.

Xcode needs to install some additional components. Be sure to respond positively to that prompt and wait until the operation has finished. After the app launches for the first time, you can quit it because we now have the required software support in place.

6) We must disable Find My iPhone before installing any new iOS software. Launch Settings on the iOS device and tap your Apple ID bio at the top. Next, tap iCloud, choose Find My iPhone/iPad from the list and slide the switch next to Find My iPhone/iPad to the OFF position. Lastly, type in your Apple ID password and hit Turn Off to confirm the operation.

7) Now launch iTunes from the Dock or your Applications folder.

Only encrypted backups store sensitive personal data such as your Health database or saved passwords for any Wi-Fi networks your device has connected to in the past.

Archiving ensures the backup file doesn’t get overwritten by any subsequent backups in the future. Archived backups are distinguished from normal ones with a timestamp.

Should anything go terribly wrong with our beta installation, we can always comfortably downgrade back to our previous iOS version without worrying about losing any precious data.

iTunes will now install the beta onto your iOS device.

Now’s a good time to grab yourself a sandwich or check your email. The iOS device may automatically restart a few times during the install process. Do not turn it off or unplug it from the computer until the update is complete.

How to install iOS or iPadOS 13 beta using macOS Catalina 10.15 beta

This method is recommended for people who’d like to install the macOS Catalina 10.15 beta alongside the iOS or iPadOS 13 beta. It doesn’t require downloading the Xcode 11 beta at all.

1) Visit chúng tôi on your Mac and sign in with your Apple ID account.

Your computer may reboot a couple of times during the install phase. You’re wholeheartedly recommended to avoid installing the beta onto any Macs you regularly use for work and play.

Choose this course of action to run a clean copy of the macOS Catalina 10.15 beta rather than have your Mojave installation upgraded to Catalina. And don’t you worry a thing because the installer will offer to optionally transfer information from your current operating system.

5) With the macOS Catalina 10.15 beta successfully installed and booted into, visit chúng tôi in Safari and sign in with your Apple ID account.

An archived backup is never overwritten by any subsequent backups you may create on this computer. An archived backup gives you a fixed point in time to restore an iOS device from in case you want to downgrade back to the previous iOS version.

10) Launch Settings on the connected iOS device, tap your Apple ID bio at the top, hit iCloud and choose Find My iPhone/iPad from the list. Slide the switch next to Find My iPhone/iPad to the OFF position, type in your Apple ID password and tap Turn Off to confirm the operation.

Your Mac will now start installing the beta onto your iOS device.

The instal process can take a couple of minutes or more, depending on your iOS device model. Do not turn the device off or unplug it from your Mac until the update is complete.

iOS and iPadOS 13 are scheduled to release commercially this fall.

How To Install Macos Mojave Beta On Your Macbook, Imac And Mac Pro

One of the most significant announcements at Apple’s WWDC 2023 developer conference was the next iteration of macOS, which has been dubbed macOS Mojave (pronounced mo-hah-vee). I really like the new name but the upcoming features, including dark mode, the revamped app store, and desktop stacks make it even more exciting.

Devices Compatible with macOS Mojave

While Apple did boast about devices compatible with iOS 12, the company did not talk about what all generations or variants of Mac will support macOS Mojave. Apple only said that it will support computers from mid-2012 or later, including 2010 and 2012 Mac Pro models with recommended Metal-capable graphics cards

Here’s the entire list of all macOS devices that are compatible with the latest iteration of macOS update:

MacBook (early-2024 or newer)

MacBook Air (mid-2012 or newer)

MacBook Pro (mid-2012 or newer)

Mac Mini (late-2012 or newer)

iMac (late-2012 or newer)

iMac Pro (2024)

Mac Pro (late-2013, including mid-2010 and mid-2012 models with Metal-capable GPU)

Method 1: Install macOS Mojave via OTA Update

Note: Remember that all beta software has some bugs which may interfere with regular usage, so do keep that in mind before proceeding.

1. First, navigate to the download page of Apple’s Developer website and scroll down to find the macOS Mojave 10.14 beta. Tap the “Download” button next to it to download the .dmg utility file.

4. Once the download is complete, your Mac will restart and you’ll then be prompted to log back into your Apple account to start using the developer beta.

Method 2: Clean Install macOS Mojave Via USB

While installing the macOS Mojave beta via an OTA update method is the most common way to go, there’s a possibility that you might want to hit refresh on your Mac system. It means you are ready to sacrifice all your data and start anew. So, here are the steps you need to follow for a clean install:

1. First, you need a USB drive (preferably with 16GB storage). You’ll need to format the USB drive via Disk Utility using the ‘Erase’ option, where you have to keep its name and format unchanged.

2. You’ll then need the same OTA image of the macOS Mojave beta that you downloaded from the Mac App Store. Remember, you don’t need to install the image but instead, keep the files in the Applications folder.

sudo /Applications/Install macOS 10.13  volume /Volumes/Untitled –applicationpath /Applications/Install macOS 10.14 

4. You may be prompted to enter your Mac password, so just follow through and all your installation files will be moved to the USB drive.

5. Finally, restart your Mac and hold down the “Option” key to see a list of available drives and select the USB installer disk.

6. You will then see a familiar ‘Disk Utility’ window, which comes in handy for erasing your Mac’s main storage. It is a necessary step for a clean installation, which you can now complete by following the instructions on the screen.

Try Out macOS Mojave on Your Mac Computer

While we didn’t have high expectations from iOS 12, all the leaks and speculations were suggesting that macOS 10.14 will be a feature-rich update that we’ve been waiting for. Apple delivered us some of the most requested features, while simplifying and making everything else a little more handy for Mac users.
