What happens after OS X Internet Recovery without erasing disk - macos

I want to reinstall OS X Yosemite in my MacBook Pro 2015 without erasing the disk. What will I need to reinstall after the process is done? What files are not removed from my hard drive? What files ARE removed from disk?
Thanks!

Run a backup to save all of your data via Time Machine.
Reinstall OSX.
Restore your data from Time Machine if its not available after reinstall.
Run Disk Utility and have the application search and fix any permissions issues that will almost certainly occur when doing a reinstall with applications pulled from a previous install.
DON'T attempt to do a reinstall without making a backup via Time Machine to an external drive.

From #bmike:
"Almost nothing is actually removed. What happens is the installer downloads a fresh and complete set of system files - basically the things that came with the Mac out of the factory minus some iLife apps like Garageband for instance.
The installer doesn't delete any user settings, user files and doesn't even delete apps you installed.
The process is designed to make the system work whether or not you have large or small changes to the system."

Kettle / Pentaho Data Integration not usable: very slow to start up and hangs on right click

For all practical purposes, I cannot work with Kettle / Data Integration, although it is half of my new job. Does anyone have any insights?
Issue:
Kettle is very slow to launch, and immediately hangs and needs to be Force Quit when I right click on anything in the left side panel.
That is the main issue, as there are some things you can only do by right clicking on the object you want in the view panel. But I believe there is also a configuration issue. For example, when I try to create a new database connection after creating a new transformation (both from the File menu), I get this error:
“org.pentaho.ui.xul.XulException: java.lang.reflect.InvocationTargetException”
My config:
Mac OSX 10.12.6 (Sierra)
Kettle, also known as Pentaho Data Integration, version 7.1.0
What I already attempted:
Uninstall and reinstall Kettle in 2 ways:
o From the installer package on this website (which redirects to https://sourceforge.net/projects/pentaho/files/Data%20Integration/7.1/pdi-ce-7.1.0.0-12.zip/download)
Uninstall: move Data Integration folder to Trash, as well as all files and folders containing “Kettle", and then Empty Trash
o From Homebrew in the Terminal, using: brew install kettle
This way installs version 6
Uninstall: brew uninstall --force kettle
Close all apps in use, hard reboot my computer, kill memory intensive processes in Activity Monitor
Sudo purge
Notes:
Kettle takes over 1 GB of memory right away after being started.
Here is how I launch it, in Terminal, not by clicking on the .app item, because that doesn't work:
When installed from installer dmg package : /Applications/data-integration/Data\ Integration.app/Contents/MacOS/JavaApplicationStub
When installed from homebrew: spoon.sh
For all's information, I got an answer that did the trick here:

you have to rise the ram , open the spoon.sh an modify proper section about memory

Missing shutdown file on OS X

I have recently moved the shutdown file in /sbin/ directory and I lost the content of the shutdown executable.
I can't shutdown the computer because of it.
Can someone tell me where can I get this file without reinstalling the OS? Any advice for recovering\reinstalling this executable?
or can someone upload this file for me.
or copy paste the content of the file on pastebin.com
I have Yosemite 10.10
Thank you.
I'm afraid you need to reinstall the os (unless you trust someone to give you that file from the same system, and better the same model machine)
Reinstalling do not clear your personal data, it will just overwrite alla system files (adding the missing /sbin/shutdown)
If you have a recent mac you have the recovery partition. Have a read here:
https://support.apple.com/en-us/HT201314
Basically you just need to power your Mac holding down Command+R

Filesharing between OS X & Windows 10 on a htdocs directory?

I had a practical question for my own work at home. I want to use quad monitor for my coding and other work. I can do this with my macbook pro attached to external triple monitor. But it is not practical because of all the cable management and Macbook Pro is barely keeping up with the performance running it. So what I wanted to do was having my PC run triple monitor and my Macbook as forth screen. Code on my pc and share/update the files in the htdocs directory on my OS X. Like how FTP works.
I found this link: http://www.itworld.com/article/2844141/how-to-share-mac-os-x-yosemite-files-with-windows-10.html
But I'm not sure if I will face sudden obstacles in doing this with my htdocs directory or other directories where my work is stored and updated from time to time.(example:Symfony projects)
I hope I mentioned everything. Thanks in advance!
Well, you can use one of the free cloud based, file-sharig service, like Microsoft OneDrive, Google Drive or Dropbox.
But files will not be updated immediately, you need to wait few seconds (in the best case scenario). So it might get frustrating quickly.
Also, from my experience, OneDrive on Mac is not the best choice when it comes to a Symfony project - it stops working after a while, probably because a lot of cache files, so I need to restart it and it's not usable at all.
Another solution might be using a version control system (f.e. Git) - but you would be able to see the code changes only after a commit and push (and do it manually, of course).

Recovering Windows and/or system restore after faulty driver install

I installed HP sound driver yesterday and it BSOD-ed my windows and crashed it. System repair didn't help. system restore is corrupted, and startup recovery just says ""patch is preventing windows from starting". when I try to boot, it loads up to certain amount of time and then in just BSOD-s to 0x0000007b.
I disabled the new driver in registry, but it didn't help.
I then installed another windows copy on a new partition, and tried copying over the registry and system32\drivers folder, still the same issue.
Any further ideas? if I could somehow just use the files from system restore that are not corrupted, and leave the rest out, that would help but I don't know how to do that.
Reinstallation was the only way to go unfortunately. I tried replacing windows files, reintegrating registry.. nothing gave stable results. This is not a solution, as I was trying to fix the computer, not reinstall OS.

Windows Home Server backup solution

I admit this is not strictly a programming question, although I do use my WHS as a source repository server for home projects, and I'm guessing many other coders here do as well.
Does anyone have a recommendation for a good backup solution for the non-fileshare portion of Windows Home Server? All the WHS backups I've seen handle the fileshares, but none of the system files or other administrative stuff on the box.
Thanks,
Andy
Windows Home Server is designed to not need a backup of the OS. If your system drive fails, install a new drive, and then boot the WHS OS setup disc and install the OS. It will find the data on the other drives and recreate all the shared folders. You do need to do some configuring once it is back up but that is pretty small compared to not having to back it up.
One good solution for backing up the home server itself is to attach an external drive, say via USB 2.0 or eSATA. For this to work, though, you need the supporting software like Norton Ghost or something similar installed on your WHS server.
Windows Home Server Power Pack 1 (aka WHS PP1) added a feature to perform backups of the WHS shared folders to an external drive -- as you mention, this feature is only intended to do the data side and not the OS.
If you have an HP MediaSmart server, you could try the method mentioned in Quick & Easy Windows Home Server Backup and Restore. The author said it worked for him, but of course, caveat emptor. This technique has you creating a disk-image for your backup, and using that to restore from in the Recovery Disk / Restore disk process.
If you want a faster way to recover your OS and you do not have a Media Smart server, you can also check out these instructions on how to use a USB flash drive for installing WHS, and merge in the instructions found above for restoring a disk image vis-à-vis the OS Recovery disk process.
WHS OS backup solved by running two copies of WHS each on its own computer in a virtual machine with each WHS backing up the other (running in a VM makes the WHS a file thus able to be backed up and restored by WHS).
iDrive is Great and free under 2 gigs
