Which version of macOS ?

YoYotta v4 requires an Apple computer running macOS 10.15 Catalina or newer.
We suggest running the latest macOS that the Mac supports.
Even if you don't want to update to a new macOS version, we would recommend that you run the latest minor version. For example if running 10.15.2 then update to 10.15.7.

YoYotta runs on Apple Silicon and Intel Macs.
Apple Pro Video Formats 2.2.4 or newer is required for the following workflows.

• Extracting metadata, creating thumbnails and transcoding from some MXF clips.
• Finder QuickLook and Quicktime playback of most MXF files.

YoYotta Server is required for S3 object workflow and key management.
All macOS versions since Big Sur will need software drivers for SAS and FibreChannel interface cards and Thunderbolt LTO drives.
Thunderbolt LTO drives have a SAS LTO drive inside, so they will need a SAS driver.
LTO drive option TAR restore is only supported on Intel Macs.

Clean install of macOS

A good way to upgrade macOS is to add a new volume to the internal SSD (make sure there is at least 50GB space) and then perform a clean install on this new volume.
A clean install to a newer macOS version is also a good idea if you are having issues where the Mac reboots (a system panic) as this can be caused by legacy hardware drivers that are still installed.
Open Apple Disk Utility and click + to add a new volume. Then download the macOS installer and select this new volume when installing.
This Apple support page has links to all versions of macOS.
This gives you a clean install, but doesn't destroy the data on your old system. Files and apps that are needed can easily be copied from the old volume.
Once the new macOS is running then also install the SAS or FC drivers for any LTO tape hardware.
Check here for details about moving YoYotta projects and presets across to the new volume

It is quick to switch back to the old version of macOS, open System Settings - Startup Disk, select the old macOS and then reboot.
After running the new macOS for a while and tranferring any apps and data, you can remove the old volume using Disk Utility to reclaim the space.
Or if you have an old apps that require the old macOS then you can keep both volumes and switch between them as required.

macOS 10.14 Mojave + 10.13 High Sierra computers v3 only. v3 is not available for purchase.
Trade in your v3 license for a v4 subscription.
Download v3
macOS 10.12 Sierra + 10.11 El Capitan computers use v3 (214)
Download v3 (214)
macOS 10.11 has issues with SSL certificates, so it still works with v3 (214), but is not recommended.
If you cannot update the macOS, then see these instructions to enable SSL for 10.11.
Enable YoYotta SSL certificates

Computers with no support for macOS Catalina.
For these systems we would upgrading to an Apple Silicon Mac mini and move your ATTO SAS or FC card inside a Sonnet Thunderbolt enclosure.

Please get in touch with support@yoyotta.com if you need any help or have further questions.

Allow system software in System Security

New installs of drivers and system software from ATTO, OSXFUSE (developer is Benjamin Fleischer) may need approval.
You will see a message saying System Extension Blocked
Also the first time you use YoYotta to read TAR tapes on a new system, you will need to approve YoYotta System Software.
Open the Security & Privacy page in Apple System Preferences, unlock the padlock and click Allow to enable the System software to load.

You must click the Allow button locally on the Mac, clicking using remote screen sharing will not work.
If the Allow button is not shown then reboot your Mac, try again to use LTFS or TAR tapes (which will fail) and then check the Security & Privacy page again.
Also ensure that you have the latest updates to your version of macOS

Files and Folders access

When running YoYotta with newer macOS versions you may see requests to allow access to folders like Documents, Removable Volumes or Network Volumes. Please allow these requests.
Also you can enable access in Files and Folders in the Security tab as shown in the screenshot.
YoYotta does not need Full Disk Access.

Screen Sharing

YoYotta keeps the Mac awake when jobs are running.
However when working with LTO tapes it is best to also disable system sleep in System Preferences. Leaving screen sleep enabled is fine.

If using remote screen sharing, then when sharing stops the Mac can be locked and start sleeping.
To prevent this, type the following into the Apple terminal. You will need to enter your Mac account password.
sudo defaults write /Library/Preferences/com.apple.RemoteManagement RestoreMachineState -bool NO
