The Mac OS X 10.10 (Yosemite) installer fails to extract any files onto my drive:  OS X could not be installed on your computer An error occurred while extracting files from the package &quot;Essentials.pkg&quot;. Quit the installer to restart your computer and try again.  However, I have reinstalled Mac OS X 10.9.5 (Mavericks) just fine, which leads me to believe there’s something wonky going on with the installer. Judging by the comments on , it seems like this error might be occurring with people who have installed SSDs in their old MacBooks. I have a mid-2010 MacBook with a 512GB SSD in the main hard drive slot and a secondary 250GB HDD in the DVD drive bay. I also have installed 16GB of RAM in this laptop. So far all of the new hardware has worked fine for the past 6 months so I doubt my issues are due to faulty hardware. I am trying to perform the install on a freshly formatted partition. Here is the . Here’s  from when I was trying to upgrade the OS instead of using a freshly formatted partition.

I'm getting this error:  OS X could not be installed on your computer An error occurred while extracting files from the package &quot;Essentials.pkg&quot;. Quit the installer to restart your computer and try again.  Every time I restart, it installs until &quot;19 minutes&quot; are left and gives me the exact same error. I have no idea what to do because apparently no one else is having this problem.

I am sure many of you guys know the flashing folder icon which shows up when the Mac cannot find a drive to boot from. My 2017 MacBook Pro has this issue for some time now, but recently I found something interesting.   The MBP won't find the boot drive, as long as the battery level is at > 70%.   The Mac boots just fine at lower battery levels; no issues whatsoever. Now, the problem is, I don't want to run my MacBook via battery the whole time or keep on disconnecting the AC power when 70% is reached every time.   Does anybody have similar symptoms and did find a better solution? Do you think there is a hardware issue with my device?   I've been to the Apple store before (when I didn't knew this was connected to the battery level) and they couldn't find anything. They suggested I reinstall macOS, which of cause didn't change anything.  Edit: One detail I forgot to mention was that when I charge my MBP and close the lid, it crashes and gets really hot (fans turn on slowly). I'm not totally sure on this, but I think this also happens with lower battery levels.  Battery Info:

I have an intel Imac (early 2006).  I recently decided to install ubuntu on it as the sole OS as it was running 10.4.11 and was unable to meet my current needs.  The optical drive on it is broken,  so I downloaded the ubuntu iso,  converted it to a DMG and created a bootable flash drive.  Everything seemed to be going great.  I used gparted to wipe the hard drive and than began running the installer from the live enviro.   That's when things took a turn for the worst..  Half way through the installer crashed.  I attempted it a few more times,  but it eventually just froze solid.  I asked around what to do and was told to just reboot and try again.  Now it is not seeing the flash drive, and there is no OS to boot to,  so I'm just getting the ol' grey screen with a flashing question mark..    I bought a new 500gig external that I can format for a mac..  I'd like to try and install ubuntu on it and see if I can maybe boot the mac off it to try and fix and finish the install..    I mainly want to know how to convert an iso to a dmg using my other ubuntu machine,  but failing that,  I'm open to any suggestion.

I got a 2015 MacBook Pro from eBay. I’m trying to install Sierra from scratch (after completely formatting the SSD) but I get this strange extra step (although the install USB is vanilla and done using Apple’s own bootable usb tool) that I can’t pass (pressing continue asks me to connect to a IBM private network, which I obviously can’t do)  Does anyone have any info about this. Where is this MacBook comming from? How can I disable this remote management step? Is this a custom firmwere, or where does this come from?

I was recently gifted an old Mid 2010 Macbook Pro with the following specs listed here:    I would like to do a few things to it, but I have never owned an apple computer before and I know there are some restrictions on the hardware i can purchase to upgrade it.  These are the things I want to do  1) Upgrade Ram: Currently it has 2x2GB of RAM in it. This model is rated for up to 8GB but I have been reading online and it seems some people have been able to successfully install 16GB of RAM, so i am confused. Does anyone have a definitive statement on whether or not this Macbook Pro will work with 16GB of RAM? If it does accept 16GB total which RAM should i buy for a Macbook Pro like this? If it only accepts 8GB total which RAM should i buy? And I know the clock speed must be 1066Hz for this Macbook Pro, but can i use DDR3, or DDR4 RAM? Does the DDR type matter?  2) Install Secondary Hard Drive: I am not 100% so i need someone to inform me but i believe there is space in this Macbook Pro for a second hard drive. Does the CD Drive need to be removed in order for a second Hard Drive to be put in? Or is there simply space inside it for a second hard drive but not installed by Apple? Either way I would like to install an SSD into it and install the Operating System onto that SSD. Which SSD can i look to buy that is compatible with this  Pro?  3) Fresh install of Mac OSX: As it currently stands my friend who gave this laptop to me didn't erase his data. I am uncomfortable with this and want a fresh start. How do I do a fresh install of Mac OSX Mavericks (or should i wait for Yosemite?). Where can i buy a Disk/USB for it (or make a disk/USB for it) to do a clean install and how do i format a Macbook Pros hard drive and install fresh? Should this be done at an apple store?  4) Higher Screen Resolution: This is my lowest priority and I don't think it is possible to do without major invasive changes to the Macbook Pro but i want to know if it is possible. Currently the Max Resolution on the Device is 1440x900, i would like to know if it is possible to replace the LCD with one that is 1920x1080 for high resolution.

I want to install a new Solid State Drive (SSD) into the Mac. Can I just build in the SSD, start the MacBook in Recovery Mode and install OS X from there on?  After reading a lot on the internet I still have some doubts…  My HDD crashed, I can't repair it using disk utility or the fsck methods as mentioned on the internet.  According to  it should be possible.  I know how to replace the HDD with the SSD. I would go for the Samsung 850 EVO SSD - 500GB. My Mac is a MacBook Pro Mid 2012, model A1278.

I have 13 inch mid 2010 macbook pro. Just installed new 1T hard drive but now am hesitating on what to do next. I have my old hard drive converted to external drive and a back up drive as well.

Due to battery backups not working properly in Yosemite, I need to downgrade a machine to Mavericks. Unfortunately, this is a brand new Mac Mini and it shipped with OS X 10.10.0 installed.   I read various questions here, as well as some articles from other websites, and created a Mavericks 10.9.5 installer on a USB stick. I can boot from this USB stick on an iMac we have here, but the Mac Mini will not allow me to.   Is it even possible to run Mavericks on this machine--Macmini7,1?

I'm using OS X Yosemite - version 10.10.2. I have 1.12 TB fusion drive on my system. Recently I wanted to make a partition on my system, while making the partition on the system using disk utility some error occurred and partition was not created successfully.  The unusable partition of the disk.     The partition is not available here either.     So, here I'm not able to access the free space partition of my disk. The disk utility is not working with the free space partition. I want to resize the partition and want to have only single partition disk

I have a 128gb MacBook Air running Lion. I am constantly having issues with disc space, but have no idea what is consuming it all. When I look at the disc utility break down, it says about 80% of the used space is taken up by 'Other' while the remaining 20% is photos, music and applications.  I've searched everywhere but have no idea what is using all this space. The biggest program I have on is Photoshop and perhaps XCode. I dont have any video files and I dont even tend to save .PSDs.  Would anyone know what could be taking up this space?  Thanks!

I've just bought my first Mac, a Macbook pro(with an hdd), and I'm thinking in buying an ssd and replace the hdd. But the computer came with no dvd of the OS. I know that in the hdd there is a restore partition, but if I remove the hdd, how can I install the OS?

The box says I can add up to 3 GB (for a total of 4GB), but is this restriction hardware based, or because of the operating system?  If I upgrade to OS X 10.6 or higher, can I increase the RAM to 8 GB like the newer models?

I wanted to do a clean install and booted from OS X recovery partition. In disk utility I selected "erase" option. SSD was working correctly before that.  Now, if i startup, the only way to proceed is with Internet Recovery  since I cannot boot from hidden recovery partition. After I wait several hours for the recovery image download, I cannot see the SSD either in disk utility or OSX reinstallation.   In terminal   diskutil list   Shows only recovery image 1.8 Gb or so.  So did erase option destroy my ssd?

I was wondering if there is a way to recover photos and things alike from a MacBook after reinstalling the OS X.  Like when you reinstall Windows there is the "Windows.old" folder and you can recover some of the data from there.

I have downloaded the El Capitan dmg file (InstallMacOSX.dmg) provided by Apple. The expanded dmg image contains the package "InstallMacOSX.pkg" which should be run to create the El Capitan installer but fails with the following message "This version of OS X 10.11 cannot be installed on this computer." presumably because quite reasonably it would not make sense to install on top of a later version of the OS. However in this case I want to create a boot USB drive for an installation on another Mac.  I am stuck in a chicken and egg situation where I need another machine running El Capitan or earlier to create and El Capitan boot installer.

My question:   Can anyone confirm or disprove the support of NVMe drives (like the Samsung 960) by the Sintech M.2 PCIe SSD MacBook adapters for macOS Sierra and High Sierra, or would you have any information that could help me confirm or disprove this support?  Below are the results of my research so far.    SSDs comparison  "Official" MacBook SSDs  Officially supported MacBook SSDs are really expensive. For example, with the Macbook Air/Pro 2013, 2014 and 2015 models:   : $299 for , $399 for , $649 for  : $524 for 256GB, $649 for 512GB, $949 for 1TB.   Equivalent PC SSDs  Globally, an officially supported MacBook SSD (PCIe M.2 AHCI with a proprietary 12+16pin connector) cost from about $1 to $2 per GB, while equivalent PC SSD (PCIe M.2 AHCI and NVMe with a key M connector) cost from about $0.4 to $1 per GB.  NVMe:   : $196 for 512GB (low quality) : $219 for 500GB : $316 for 480GB   AHCI:   : $300 for 480GB : $450 for 512GB   So standard PCIe M.2 devices seems to be up to 3x cheaper than the MacBook PCIe M.2 SSD. Plus, NVMe SSD are globally way faster.    NVMe SSD compatibility?  Connector adapter  At first for the connector, I often seen the   recommended to use the AHCI SSD above in a MacBook Air/Pro. The product page clearly stipules only compatible with a limited set of AHCI SSDs, but I do not see any reason for these "incompatibilities", as there is no other software/hardware standards for the PCIe M.2 AHCI models. It seems they simply give as compatible the list of the AHCI SSDs they've tested, and as incompatible the most known NVMe SSD models.  Interface compatibility  Then for the interface, what I understand from AHCI/NVMe is that it is only a controller interface, depending on the system drivers on the MacBook and not on the hardware itself.  Which seems to be consistant with:     I emailed the store which sell that adapter and problem is that macOS doesn't support 3rd party NVMe SSDs, but Windows 10 and Linux do.      -- From a  on a upgrade video with a AHCI SSD and the Sintech adapter.   So Sintech may have given these NVMe SSD as incompatible not because of the adapter incompatibility, but because of the destination OS incompatibility.  System support  Finally for the system, macOS now support NVMe SSDs, from unofficially OSX El Capitan (with a  to boot) and natively macOS High Sierra (even as boot, see an article about the  and a confirmation from the ).  I sent an email to Sintech to get more informations on their adapter. I got a reply with some references (added to this post), but no answer since.  Edit (23/06):     Unfortunately, we are busy in other projects, and still can't get new system to test it.     Similar researches  After I created this post, I seen there is some people with the same question in other communities, waiting at the same step. I share the links there in case of some of them got a return from a test with the Sintech adapter or an other one.  On    Por Chumjan (02/27/2016):     I think about to upgrade. Samsung 950 pro is interesting. But i'm not sure it can use for this model.  trumanhw (12/21/2016):     You can buy an adapter from M.2 to MBPr or Air for about $20... (...) The REAL question is if the NVMe protocol will be a hiccup (as in, I don't personally know that answer) ... and if it'll get the full speed of the 950. In principle, I don't see why it wouldn't. And I WILL be testing this out.  Fabio (06/10/2017):     [ About the patch ]. It is meant to be used on hackintosh but I think it might work on a macbook pro from 2015 with the adapter and a nvme ssd like the samsung 960/950 evo/pro. If someone tries or has tried it please let me know.

I received a new HDD from my uncle, RAW file system. Tried CHKDSK, but it didn't work because of the RAW file system.      Update  I ran SpinRite 6 overnight and it got nowhere. Stayed at 0% for the whole 10 hours. SpinRite also gave me a notification that this drive is most probably toast. I think I am going to throw this drive away.
