What is the speed for OS 10.10 on 13-inch, early 2009

My 13-inch, Early 2009 MacBook runs with OS 10.9.5 basically OK on speed, and it's a very good, loaded with the fine software is useful but old and slow sometimes with all additional popups and deflect and is very nervous about the links I don't want and mail that I didn't delete.

The system is pushing me to the update/update 10.10 and I continue to resist the Apple push, the fear of losing what I have and I'm really happy with.

I was looking for the answer among existing similar concerns, but did not get the simple answer and clear what will I win by the new OS 10.10.

My fear is real or just scared?

Apple has removed 10.10.5 and 10.11.5 from the App Store, so only your option upgrade is 10.12.

  • I use my MacBook Air as a desktop computer. Should I leave the charger plugged all the time or should I drain the battery and then recharge? What is the best for the battery?

    I use my MacBook Air as a desktop computer. Should I leave the charger plugged all the time or should I drain the battery and then recharge? What is the best for the battery?

    Keep the computer plugged in whenever possible.

    If you keep the computer always connected, make sure that at least twice a month

    Run it on battery until battery charge level falls to about 40-50%.

    Please don't completely discharge the battery. Discharge the battery completely will reduce wear and tear on the battery.

    Citing at the bottom of the linked article.

    "The question is often asked:" should I disconnect my laptop from the mains when not in service? Under normal circumstances it should not be necessary because as soon as the lithium-ion battery is full, a properly functioning charger will stop the load and load the pad will only engage when the battery voltage drops to a low level. Most of the users do not remove AC power, and this practice is safe. »

  • What is the recommended for El Capitan recovery process?

    What is the recommended for El Capitan recovery process?

    I just upgraded directly from Mountain Lion, and I see that my recovery disc has disappeared.  My recovery disk wizard is only good for Lion and Mountain Lion.  I searched Apple.com and found a complicated process by which I could use the Console and create a bootdisk with the option reinstall, but I can't believe that this is the recommended option for a common user?

    So is time machine bygones?  I noticed that it is dimmed in the Menu bar?

    Certainly, you can restore El Capitan as you would with any other version of OS X - using the HD Recovery. I have no idea why your Recovery HD disappeared. Usually this would cause by user error. However, you can create a standalone install OS X on a USB FlashDrive for emergency use. This has been an option because at least Mavericks:

    Do your own installation of El Capitan using the El Capitan tool flash drive:

    You can create an installer of flash of El Capitan via the Terminal drive. El Capitan has its own manufacturer Installer integrated that you use via the Terminal:

    You'll need a freshly partitioned and formatted at least 8GBs. USB flash drive leave the name of the flash drive on the system by default, "Untitled." Do not change this name. Wait as the full process that will take some time.

    Open the Terminal in the Utilities folder. Copy and paste the following line in its entirety in the Terminal window.

    sudo/Applications/Install\ OS\ El\ Capitan.app/Contents/Resources/createinstallmedia--volume/Volumes/Untitled--applicationpath X\ "/ Applications/install OS X El Capitan.app.

    Press RETURN, enter the admin password (will not resonate to the window) then press RETURN again.

    You must have setup in your Applications folder or change the paths in the command line above.

    You can do the same thing for Yosemite by making the appropriate substitute for the installer in the above command line:

    Make your own Yosemite flash Installer drive using the tool of Yosemite:

    You can create an installer of the Yosemite via the Terminal flash drive. Yosemite has its own manufacturer Installer integrated that you use via the Terminal:

    You'll need a freshly partitioned and formatted at least 8GBs. USB flash drive leave the name of the flash drive on the system by default, "Untitled." Do not change this name. Wait as the full process that will take some time.

    Open the Terminal in the Utilities folder. Copy and paste the following line in its entirety in the Terminal window.

    sudo/Applications/Install\ OS\ Yosemite.app/Contents/Resources/createinstallmedia--volume/Volumes/Untitled--applicationpath/Applications/Install\ OS\ Yosemite.app X\ X\

    Press RETURN, enter the admin password (will not resonate to the window) then press RETURN again.

    You must have setup in your Applications folder or change the paths in the command line above.

    In addition, to Yosemite and earlier you can try using DiskMaker X.

    Hello Mohan,

    ·         You did changes to the computer before the show?

    These errors often occur if there are incorrect BIOS (Basic Input\Output System) settings.

    Method 1: Check if the computer startup options are changed in the BIOS. You can set the hard drive as the first boot device. In addition, make sure that this option "Wake on LAN" or one similar to it is off.

    Method 2: Load default BIOS (Basic Input\Output System) settings, and then restart the computer.

     

    Important : Change/update BIOS can be a complicated process, and if an error occurs, your computer could be rendered inoperative. Be sure to observe the instructions of the manufacturer.

    If the Office programs are preinstalled on your computer, you will need to contact the manufacter of the computer to see if you have the product key to reinstall on your computer.

    Otherwise, since they have been deleted, you will need to reinstall using original diskettes or purchase need office products.
