Downgrading OS X without losing anything – WriteKay Kay Yin Everywhere is within walking distance. WriteKay HiKay Downgrading OS X without losing anything Written on August 13, 2015 Some have asked me how to downgrade OS X without losing any files, applications and data. I decided to write a unenduring tutorial of downgrading from OS X 10.10 to 10.9. The same process applies for downgrading from 10.11 to 10.10. Preparation 1) You now have OS X 10.10 with personal documents and apps. You want to go when to 10.9 but alimony everything. 2) You need a 10.9 installation USB drive. You can make it by pursuit this tutorial. https://support.apple.com/en-us/HT201372 3) If you use iWork’14 (Pages 5.5.x, Numbers 3.5.x, Keynote 6.5.x) outside of iCloud Drive, unshut those documents. Go to File — Advanced —TranspirationFile Type, and transpiration them from “Single File” to “Package” one by one. If you use iWork’15 (Pages 5.6.x, Numbers 3.6.x, Keynote 6.6.x), export your documents to Word, Excel and PowerPoint one by one. 4) If you have Final Cut Pro libraries that are in 10.2.x format, unshut them, segregate File — Export XML— and save them as XML (version 1.4). If you use iMovie, finish all your projects and export those into media files. Preservation (of Data) 5) First, disable FileVault encryption if it is enabled. Then disable Core Storage if it is enabled. 6) Power off your Mac. Hold option key.Segregateto marching from the newly-created USB drive. 7) When presented with multiple Options, segregate Utilities - Terminal. 8) Navigate to your Mac’s local nonflexible momentum partition (which contains 10.10) by typing “cd ..” multiple times, then type in “cd Volumes”. Then type in “ls”. Type in “cd + ‘name of your drive’(does not include plus sign or quotation mark)” 9) Type in the pursuit commands. Once you finish typing one line, printing enter and wait for the writ to complete. Some processes may take a few mintues. mv Applications App1 mv Library Lib1 mv System Sys1 mv Users User1 sudo rm -rf .DocumentRevisions-V100 sudo rm -rf .Spotlight-V100 sudo rm -rf .fseventsd sudo rm -rf .Trashes sudo rm -rf .vol sudo rm -rf bin sudo rm -rf cores sudo rm -rf etc sudo rm -rf home sudo rm -rf mach_kernel sudo rm -rf net sudo rm -rf Network sudo rm -rf private sudo rm -rf sbin sudo rm -rf tmp sudo rm -rf usr sudo rm -rf var sudo rm -rf Volumes Downgrade (of OS X) 10) Then tropical Terminal and segregate to “Install/Reinstall OS X”. 11) The installation will proceed as normal. Set up worth like how you set up a new Mac. Restoration (of Data) 12) After you log in, everything is fresh. Don’t worry. Go to Finder.Segregate“Go” — “Go to folder”. Type in “/” and printing enter. 13) You’ll see a few uneaten folders, named App1, Lib1, Sys1 and User1. Those are where our preserved user data are located in. 14) Go to App1. Move every non-system app (apps you’ve installed yourself) to the very local Applications folder. Some app may no longer be uniform with that previous version of OS X. Trash them [except Xcode if you use it] and re-download legacy uniform version, either through Mac App Store, or software vendor. When done, trash “App1” folder. 15) Go to Lib1 and go to “Application Support”. You only need to move supporting files from here to /Library/Application Support if you have installed non-sandboxed OS X apps (usually from clunky pkg packages instead of drag-and-drop dmg images or Mac App Store apps, such as legacy versions of Office for Mac, professional software like ProTools or Adobe apps). 16) Now it’s the Users folder. If you squatter denied permission, right click on your previous user folder, segregate “Get Info”. Then click the lock icon, enter your password to unlock changes. Delete everything but “everyone”, and transpiration Privilege to “Read & Write”. If you don’t squatter denied permission, proceed. 17) Go to your old user folder, again, move/drag every document (or data) into the very new user folder. 18) Photos app’s library will not be uniform with iPhoto. If you put everything under Photos, right click the Library, segregate to “Show Package Contents”, and stilt out JPEG files from “Masters” folder. Then reimport them to a wipe iPhoto library. You will lose all non-destructive edits, albums, slideshows, squatter data and other organizations. They need to be regenerated or recreated. 19) iTunes library may not unshut in a previous version of iTunes that come bundled with that version of OS X. Download the latest version of iTunes either in Mac App Store (10.8 or above), through Software Update (before 10.8) or from iTunes.com. If you’ve used TinyUmbrella to replacement firmware APTickets before, be sure to get all data from a subconscious folder at “/Users/old user name/.shsh”. 20) [Optional] Launch Final Cut Pro X 10.1.4. Import those previously exported XML files so that you’ll alimony wangle to all your projects. 21) [Optional] Download and compile XcodePostFacto by landonf to unshut and modify your newer Xcode projects. After towers the xpf-bootstrap.framework, Xcode can be launched from the command-line: env DYLD_INSERT_LIBRARIES=$ABSOLUTE_PATH_TO_FRAMEWORK/xpf-bootstrap.framework/xpf-bootstrap /Applications/Xcode.app/Contents/MacOS/Xcode 22) Now you need to segregate “Go” — “Go to folder” again. This time, type in “/Users/old user name/Library” and printing enter. You’ll see app preferences, support files and perhaps documents. Knowing what’s necessary and what’s not requires some understanding well-nigh how OS X works. Here are some of the folders that contain useful data: Application Support — Again, you only need to move supporting files from here to ~/Library/Application Support if you have installed non-sandboxed OS X apps. Notice this time, they should be moved to “~/Library/Application Support”, rather than “/Library/Application Support” as they should be in user folder. Common app that need doing so is Adobe. Do NOT move everything in this folder to your previous system. Just do so for pro apps/clunky old pkg apps. Containers — Sandboxed apps save data, caches and settings here. For example, epubs in iBooks is saved under com.apple.iBooksX. Data are usually in “Documents” folder, and preferences are often in “Library” folder. Again, they may not be directly uniform with older counterparts, expressly if they’re system build-in apps. You may need something like “sqlitebrowser” to unshut databases/configuration profiles (in this case, bookmarks and annotations will only be wieldy through reading sqlite databases, but books themselves can be repackaged as epub and reimported). Fonts — Fonts you’ve installed. You can just move them to “~/Library/Fonts” without any problems. Keychains — Saved passwords. Don’t directly move them. Instead, reprinting them to a unscratched location. Then import them through KeychainWangleapp. Mobile Documents — Everything you saved in iCloud Drive/iCloud Documents & Data. iCloudMomentumwill not be uniform with OS X 10.9 and below, and once your worth is updated for iCloud Drive, it can not be reverted. However, you can reprinting these documents to a unscratched location, such as the user Documents folder, and create a new iCloud account, enable Documents and Data, reprinting them when in and re-sync them. Don’t reprinting folder structure. Just reprinting your files into the correct container OS X newly generated. Safari — Bookmarks and History. You can only move “Bookmarks.plist”, “History.plist” and “TopSites.plist” plist files to “~/Library/Safari” without any problems. Do not move any other files. Widgets — Move widgets out to a unscratched location. Double click to reinstall. I know you may be tempted to move stuff I haven’t mentioned here, but trust me, unless you’re 100% certain, don’t move them to your current Users folder. Most of the other stuff can and will be regenerated, such as iLife stuff, default preferences or caches. Hint: “sqlitebrowser” can unshut databases/configuration profiles that are no longer uniform with previous versions of respective app counterparts. 23) Now it’s up to you if you want to leave the Users1 replacement folder there. If you think you’ve got everything, trash it. 24) Enjoy! You’ve downgraded OS X without losing any data or apps! The same tutorial is moreover posted on MacRumors Forum. I am the tragedian of this tutorial.
