Bad Sierra OS Upgrade -near ‘reinstall’ situation :-)

This morning today I just had a bad experience with my MacBook pro. I am using quite old -early 2011- version of MacBook Pro for daily work and so far it is working fine. It is running on Sierra OS and I have no complaint about it until this morning.

I recently received an alert from the system that new software updated available and last week -I think- I did follow the instruction to updated my mac. The update went fine, no problem until this morning. I shut down the machine normally yesterday. But this morning when I try to boot my machine, something strange happened. I cannot find my users to log in! Not only that, I cannot find others users list as well. There were only two blank field where I tried to enter my user name and my password (it is an admin account) and it is not working. Tried to reboot it several times but no luck.

I did some quick research on google and found that some users had experienced this same issues sometimes in year 2016 on Sierra 10.12.2. That’s weird considering that I only have this problem on recent Sierra update -10.12.5 last week end!

There were some recommendations provided on the internet or apple support. After read it thoroughly -well to reinstall the OS is my very last option- I decided to do this recommendation. At least I try it first 🙂



To reset the password for a user in recovery mode, and to keep data, you may type ‘resetpassword‘ into the terminal which can be found by clicking on the top menu under utilities

Note that while doing the password reset steps, you will be asked to provide your iCloud password.

I never tried to use the mac recovery mode before. Basically during the booting, you have to press Cmd-R buttons and you will have the recovery screen. There you can choose your recovery options including recovery from backup (Mac call it as “Time Machine”).

So I followed the instruction and did the “resetpassword” steps, restart and try my new password but still not working. After some more booting, and finally it works!

Not sure what’s really happened, but some said that the update has affected the user account folder on mac.

I have used OSX since Mountain Lion in 2011. Based on my experience, the worst version is Maverick. I think I wrote about that in this blog also. After some versions upgrade, this is the first problem I had. Quite disappointing though.

But I guess it is still better that Windows, I think 🙂

Happy Birthday Mac!

Seperti yang diumumkan di website resmi Apple511px-Macintosh_128k_transparency, hari ini adalah hari ulang tahun Macintosh.  Hari ini pada tahun 1984, Macintosh pertama kali diumumkan.

Kalau diingat-ingat, pertama kali saya tahu ada komputer yang namanya Mac adalah sekitar tahun 1999/2000. Di meja kerja rekan saya yang jadi web designer. Dan saya benar-benar memiliki dan memakai Mac sejak 2011. Lama sekali ya ..:-)

Jadi ingat candaan hanya ada dua jenis pengguna komputer di dunia ini:

  1. Pengguna Mac
  2. Pengguna yang ingin pakai Mac

Anda termasuk yang mana ?  Hohoho

Happy b-day Mac!

Extent Battery Life -Macbook Pro

Issue umur battery adalah issue populer bagi pengguna notebook. Karena sifatnya yang mobile maka sangat wajar bila pengguna notebook berharap notebooknya mampu bertahan lama tanpa “infus” (tanpa plug ke listrik). Bahkan salah satu indikator bagus tidaknya sebuah notebook adalah ketahanan battery-nya.

Tapi, battery perlu dipelihara. Salah memperlakukan battery, maka umur battery akan cepat berkurang. Jika demikian, pengguna notebook akan dipaksa untuk merogoh “kocek” yang lumayan dalam untuk membeli battery baru. Atau pilihan lainnya, bertahan dengan sistem “infus” 🙂

Ini juga menjadi kekuatiran saya. Saya tidak ingin battery Macbook Pro saya cepat rusak, murni karena harganya yang bakal lumayan bikin pening 🙂 Karena itu saya googling, dan dari berbagai macam tips yang beredar di mbah google sepertinya berikut ini yang paling “afdol” (kalau kata si Kemal, peserta Stand Up Commedy Indonesia 2) karena tertulis di website Apple. Tapi sepertinya ini juga applicable untuk battery-battery notebook lain. CMIIW.

Secara summary, perlu dilakukan pengosongan secara rutin. Satu bulan sekali sudah cukup. Caranya sbb:

PowerBook G4 (15-inch Double-Layer SD), MacBook (all models), and MacBook Pro (all models) 

The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) and any model of MacBook or MacBook Pro has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:

  1. Plug in the power adapter and fully charge your PowerBook’s battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
  2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
  3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
  4. At this point, save your work.  Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
  5. Turn off the computer or allow it to sleep for five hours or more.
  6. Connect the power adapter and leave it connected until the battery is fully charged again.

Tip: When the battery reaches “empty”, the computer is forced into sleep mode. The battery actually keeps back a reserve beyond “empty”, to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, with the safe sleep function introduced in the PowerBook G4 (15-inch Double-Layer SD) computers, the computer’s memory contents have been saved to the hard drive. When power is restored, the computer returns itself to its pre-sleep state using the safe sleep image on the hard drive.
