• Impossible to install MacOS Sierra

  Hey, I tried to clean install macOS Sierra. I downloaded the file from the app store, created a bootable USB key. Then I erased my drive hard and then tried to start. However I'm unable to install it. Sometimes with a sign even before X that I get to the installation option.

  Then I tried to restore from the internet, and which also failed.

• Downloaded the new MacOS Sierra, but cannot install it

  Hello!

  The morning I downloaded the new OS Sierra from AppStore. The download is complete, I started to install. Amidst this, a message appeared and he said I don't have enough hard disk space. Well, fortunately I managed to start the previous operating system and everything works normally.

  The problem is the following- I always update the operating system more recent. I open AppStore, OS Sierra search and it says downloaded. But I can not start the installation process in any case .

  In the finder, I noticed that there are new 'macOS Install Data' folder under Macintosh HD. Should I delete this, so I can re-download from AppStore new OS and then install? Or how can I start the installation again process?

  Thank you!

  Look in your Applications folder for "Install macOS Sierra." This is where the installer is placed when it is downloaded. It is normally deleted once the update is complete, but may still be there.

  I would also say that you look through the problems on this forum other users have experienced so you can decide if you want to join them.

• macOS Sierra - calendar Agent Crash

  I installed macOS Sierra on my MBP 8.3 (17 "end 2011) - 16 GB of RAM. 1 TB SSD.

  After you have identified a problem with a Logitech mouse driver (and delete) I stopped for a few days to attend to other things.

  Restart today, I had a few problems:

  1. the backlight of the screen did not come until after I entered the word password (took a few reboots hard to understand what was going on.  Once I entered the password, backlight restarted and has been authorized since, even after stop and restart.  Weird!

  2. the problem that won't go away, it's with the agent of the calendar.  He has appeared as a couple of notifications - a single event, reminder of a task.  I rejected the two of them, but they came back several times.  The console log shows the following:

• macOS Sierra hangs after startup

  I have a macbook pro 15 inch mid 2014 retina

  After that I installed macos sierra my macbook freezes after startup for about 10 min before things become normal after shots completely from the OS, I tried the P + R command cmd startup items cleaning + option and I checked the ram which is normal usage, but none of the above has worked

  Stop

  Disconnect all external devices

  Restart in safe mode

  Try safe mode if your Mac does not end commissioning - Apple Support

  then restart normally, yet disconnected devices.

• Installation of macOS Sierra results in the error message "load installer has no signature verification.

  I tried to do a clean install of Sierra several times and each time Setup reaches the end and then displays the message "the responsibility of the installer has no signature verification. This leaves the computer without a bootable Mac OS version.

  The first Apple support guy that I talked to said to make a recovery of the internet. The problem here is tries to install El Capitan, but never finished. The countdown reaches 0, then goes up to about 30 minutes back. It just keeps doing hours and hours.

  The second Apple support guy that I talked to said to do a regular restore (CMD + R), but it always goes to the recovery of the internet. I'm guessing that there is no restore partition.

  The computer has 10 Windows installed on a Bootcamp partition, and that seems to work very well. I can't installed macOS.

  The computer is a mid-2015 15 "MacBook Pro. I use the disk utility installation program to format the Macintosh HD partition. I used the El Capitan terminal Installer set the hour correct system. I tried to install using another USB port.

  I would appreciate help.

• macOS Sierra upgrade questions

  Problems of bad battery life updated since El Capitan with macOS Sierra. "100% charged drains battery fast on Sierra for 2-3 hours only. Before the mac update OS Sierra, he could stay for 8-9 hours,". If we installed macOS Sierra and noticed that the battery life is empty very quickly on MacBook Air/Pro, iMac etc, please help me to solve the problem of this problems.

  Hey there,

  Nothing but hurt. It is a common problem in the Sierra. One of the reasons, you must take off the coast about obtaining the latest software. It can be a bit much. If I remember correctly, they do not have the issues of EL CAP battery until le.3 ou.4 updated. (this is the solution that allowed the 8-9) I would recommend just downgrading to El Cap, as I can't imagine that the loss in the life of the battery is useful for siri.   Just my 2 cents.
