I am running OSX 10.9.5 on an iMac and have the most recent versions of Vienna Instruments, Directory Manager and my three libraries. I have removed all folders in the Directory Manager and then dragged the individual library folders containing their respective.dat files back to Directory Manager.
There are actually four different types of macOS / OS X / Mac OS X System Updates.Types Of macOS / OS X / Mac OS X System Updates
- System Specific = If a new Mac gets released just before/after an OS update then Apple may release a 'System Specific' macOS / OS X / Mac OS X system update. Examples of system specific updates include:
- Mac OS X 10.6.7 update for MacBook Pro (Early 2011 model)
- Mac OS X 10.6.7 update for iMac (Early 2011 models)
- OS X 10.7.1 update for Mac mini / MacBook Air (Mid 2011 models)
- Model Specific = If a new Mac gets released before the next OS update and there are significant software updates available for that particular model, or there is a specific fix for an Apple product prior to the next available combo update, Apple may release a 'Model Specific' software update. Examples of model specific software updates include:
- iMac Graphics Update for iMac (Late 2013 and Retina models)
- MacBook Pro Software Update 1.4 for MacBook Pro (Early 2011 model)
- Security Update = Security updates contain very important patches to vulnerable parts of the system. Where possible you should always install security updates, sooner rather than later. NOTE: Security updates for the latest version of macOS will usually get rolled into the next 'Combo' update. Security updates for older OSes usually get rolled into the next security update (effectively creating a combo security update).
- macOS 11 - included in the macOS 11.5.1 Installer (or go to Apple menu > System Preferences > Software Update and install the 11.5.1 update)
- macOS 10.15 - included in the macOS 10.15.7 Combo Update + Security Update 2021-004 for Catalina
- macOS 10.14 - included in the macOS 10.14.6 Combo Update + Security Update 2021-005 for Mojave
- SECURITY WARNING: macOS 10.13 and earlier are no longer supported with security updates - see our securing older operating systems article.
- Delta = This type of update is available going from one incremental version of macOS / OS X / Mac OS X to the next e.g. from OS X 10.10.2 to 10.10.3. The size of a Delta update may be different for different computers. NOTE: We do not recommend installing 'Delta' updates because far more problems are reported after installing delta updates than combo updates.
- Combo = The latest 'Combo' update is what we always recommend installing because it will make sure all previous updates and patches are applied correctly/installed as well as installing the latest ones.

Instructions for creating an emergency macOS boot disk
Creating An Emergency Boot Drive For macOS / OS X / Mac OS X
An Emergency Boot Drive is useful if you maintain multiple Macintosh computers or just want something that can boot your Mac in an emergency. The basic principle is that the device:- is small and portable
- doesn't need a power supply
- has a slim but most up-to-date version of macOS / OS X / Mac OS X you need (so it can boot all supported Macs)
- Has various software utilities on it that you might need in an emergency
NOTE: This process can be used for multiple types of storage hardware including hard disks, Sold State Drives (SSDs), SD cards or USB sticks/flash drives.
NOTE: It is best that the volume/partition you are going to use must be at least 20GB in size. This is to allow for additional software to be installed and to be able to install macOS / OS X / Mac OS X 'Combo' System Updates (see below).
NOTE: You will want to consider the connection type/device depending on the Macs supported:
- USB - only Intel Macs can boot from USB devices and there are different versions of USB, some of which require specialised cables/connectors/adaptors
- Thunderbolt 3 - this is very fast but it is only compatible with modern Macs and requires specialised cables/connectors/adaptors
- Thunderbolt 1/2 - this is fast but it is only compatible with modern Macs
- FireWire 400/800
- eSATA - this will be fast but are very model specific so not generally recommended
- SD card - only Intel Macs can boot from SD cards
Diskwarrior 10.9.5 Os
Some recommended external, portable drives include:- G-Tech G-Drive mobile 5400rpm USB 3 + FireWire 800
- 500GB (model number = GDMOCEA5001ADB | part code = 0G02384)
- 750GB (model number = GDMOCEA7501ADB | part code = 0G02388)
- 1TB (model number = GDMOCEA10001ADB | part code = 0G02392)
- G-Tech G-Drive mini 7200rpm USB 3 + FireWire 800
- 500GB (model number = GDRMU3EA5001BDB | part code = 0G02569)
- 750GB (model number = GDRMU3EA7501BDB | part code = 0G02573)
- 1TB (model number = GDRMU3EA10001BDB | part code = 0G02577)
- LaCie Rugged Triple USB 3 + FireWire 800 NOTE: We do not recommend the LaCie Rugged Triple 1.5TB or 2TB models as they use two hard disks in RAID 0 mode which is catastrophic for your data if either drive fails.
- 500GB 5400rpm (part code = 301982)
- 500GB 7200rpm (part code = 301983)
- 1TB 5400rpm (part code = 301984)
- For modern Intel systems create a macOS X 10.12 or later volume on a GUID Partition Table storage device - format the volume as 'Mac OS Extended' and not 'APFS'
- For intermediate Intel systems (Core 2 Duo / i3, i5, i7) create an OS X 10.10 volume on a GUID Partition Table storage device - this has the best version of Disk Utility
- For old Intel systems (Core Duo / Core Solo) create a Mac OS X 10.6.8 volume on a GUID Partition Table storage device.
- For modern PowerPC systems (G4 1GHz or higher / G5) create a Mac OS X 10.5.8 volume on an Apple Partition Map storage device.
- For very old PowerPC systems (G3, G4 667MHz or slower) create a Mac OS X 10.3.9 volume on an Apple Partition Map storage device.
- If you are going to create a drive with multiple boot partitions for both PowerPC and Intel based Macs use Apple Partition Map. Then install PowerPC operating systems (10.3, 10.4 and/or 10.5) as required using a PowerPC computer. Then use an Intel Mac to install 10.6 and/or 10.7 as required. If you cannot install 10.6/10.7 to the external device install it to the local hard disk in the computer and then clone the install to the external device.
Setting Up An Emergency Boot Drive
Diskwarrior 10.9.5 For Mac
NOTE: External USB hard disks/sticks/flash drives and/or SD Card boot drives only work on Intel Macs.- Partition Your Device. NOTE: If the device has a large storage capacity e.g. 80GB+ create multiple partitions (the emergency boot partition only needs to be big enough to install/update macOS / OS X / Mac OS X and put your utilities on it so 30-40GB should be adequate). If the storage device is really large e.g. 200GB+ you could create multiple emergency boot partitions for different Macs you support e.g. (one for 10.5, 10.6 and 10.7) and you could also create one large partition for your software library/installers/updates.
- Install macOS / OS X / Mac OS X for the first time to your device. NOTE: You do not need to install the complete macOS / OS X / Mac OS X. At the 'Customization' stage:
- OS X 10.7 or later > There are no customisation options.
- Mac OS X 10.6 > choose the following options:
- TICK 'Essential System Software' (usually ticked for you by default)
- untick Printer Support (or just choose/tick the printers you may need)
- untick Additional Fonts
- untick Langauge Translations
- untick X11
- untick Rosetta
- untick QuickTime 7
- Mac OS X 10.5 > choose the following options:
- TICK 'Essential System Software' (usually ticked for you by default)
- untick Printer Drivers (or just choose/tick the printers you may need)
- untick Additional Fonts
- untick Langauge Translations
- untick X11
- Once macOS / OS X / Mac OS X has been installed and your computer has restarted boot from the Emergency Boot Drive (use System Preferences > Startup Disk).
- Download and install the latest macOS / OS X / Mac OS X 'Combo' Update
- List of macOS 11
ComboUpdates (latest version = 11.5.1) - List of macOS 10.15 Combo Updates (latest version = 10.15.7)
