terminal – Has the Unix parameter name SystemAudioVolume in El Capitan been changed to SystemAudioVolume DB?

I try to change the start tone. When I checked the setting with:

sudo nvram -p

A setting for SystemAudioVolume DB% ee is returned

I entered:

    sudo nvram SystemAudioVolume=%00

If I check that again with sudo nvram -p

Both names appear in the list:

SystemAudioVolume DB ….% ee

SystemAudioVolume ….% 00 (accepted my setting but did not stop the sound)

Should I try to set SystemAudioVolume DB instead?

If so, is that the right way?

sudo nvram SystemAudioVolumeDB=%aa

(No place in front of DB.) Does anyone know the right area for it?
My computer is old, but I do not want to break it.

Hard Disk – When attempting to install OS X El Capitan, an error occurred when an external hard disk needed the GUID partition table scheme

I have an old MacBook Air with Mac OS X Lion 10.7.5 (11G63) software. I'm trying to install the OS X El Capitan, but have problems. At first there was not enough memory on the Mac (even though I deleted everything I can find), so I tried to use several disks that failed for some reason. Then today I got a new external 2T Adata hard drive and now it says

"This disk does not use the GUID partition table scheme." Use the Disk Utility to change the partition scheme, select the disk, select the partition tab, select the volume scheme, and then click Options. "

I go to Disk Utility and the Partition tab and lose myself from here. Choosing this disk also sounds like a desperate situation: "To delete and partition the selected disk, select a layout from the Partition Layout pop-up menu, set the options for each partition and click You can not change the size of the partitions on this disk because the master boot record partitioning scheme is used, this partition can not be changed. "

Just spent a bunch on this hard drive says my other hard drive that it does not work because it is the same hard drive that is used for time machines. Tried another and did not work, I think it was not compatible with apples. Am I just unlucky with hard drives? I've deleted everything I can find on my computer (including Recycle Bin), but it still says I have all those photos, movies, and music somewhere I can not find anywhere. If I had enough space on my empty computer, I would not have to worry about disks … Arggh. I just want to install El Capitan so I can update my Safari or Chrome. So far everything has problems and websites are not working properly.

Please help!

macos – El Capitan clean install on an older iMac?

I have an old iMac (Model 2010), which our working group has withdrawn. My colleague wants to use it for her son. I migrated all the data to a new iMac, deleted the drive, and reinitialized the recovery partition. After the AppleID check, the iMac states that El Capitan is "temporarily unavailable". Apple Help states that you use Cmd-R to avoid linking my AppleID to the computer. Without AppleID login I can not get to the installation point. Apple Help states using Internet Recovery instead. This model does not seem to support Internet recovery. I dont get any further. I'm totally at a loss. I tried to reset everything that can be reset, to find another AppleID, another identical computer on which El Capitan is installed, and to download the El Capitan installer to check that the macOS version was running with the Purchase history of the used AppleID is related … that is absolutely ridiculous. I have an identical 2010 home iMac that my son uses as a minecraft box. I used it, deleted the drive, and did an installation of the recovery partition. I can not understand why it worked then, but now it fails. What am I missing – or has Apple made changes, so that it is now impossible to install this operating system on hardware that supports nothing higher?

No keychain can be found to save * Network * Macbook Pro (el capitan 2010)

My MacBook has issues with the keychain. I put it in an apple shop and it was not fixed (its solution is to delete everything from the user and set up a new user and transfer all my files between the users).

Basically, every time I try to connect to my Wi-Fi, I have to re-enter the password … As soon as I close the lid, the connection is disconnected and I have to re-enter the password.

All my keychains have been deleted. In a previous article I read, I want to access the keychain. In addition, the current keychains are reset to the default settings.

I also called Apple, but they said, because they can not tell you how to do it in 2010 (but it's really easy) … a little helpful comment.

If anyone knows how to solve it, I am very grateful.

Upgrade from Snow Leopard to El Capitan: Hard drive can not be selected in the installer

description of the problem

I am trying to update my MacBook (7.1) from Snow Leopard (10.6.8) to El Capitan. I've got the El Capitan installer from the App Store, but if I can do it, I can not choose my hard disk to install. The icon for my hard drive is "grayed out" and when I try to click it, the following message appears: "This hard drive can not be used to start your computer."

Installation dialog box

What I tried

With Disk Utility, I checked both the disk permissions and the hard disk itself. I also tried deleting the installer from the App Store and downloading it again. I do not know what else to do. I have a Time Machine backup on an external drive, but I do not have a Snow Leopard installation disk. I am at a loss.

macos – Macbook Pro Mid-2012 does not work anymore after upgrading from El Capitan to Mojave

I have a mid-2013 mid-range MacBook Pro. I had updated my original configuration to use a 512GB SSD (Crucial MX200 SSD) and an 8GB Ram that ran perfectly on El Capitan.

Last week I tried to move from El Capitan to Mojave. I tried this because my Mac crashed all the time and I wanted to check if the upgrade would help. It turned out that the upgrade failed. I get the error dialog "MacOS could not be installed on your computer".

I've now tried re-using the upgrade with a bootable USB drive, and reinstalling the Yosemite, El Capitan, Sierra, High Sierra, and Mojave versions with a bootable USB drive. Everything fails. Even attempting to use the recovery mode of macOS to return to inventory configuration fails. I do not know what to do now. Any help would be great! 🙂

el capitan – App-specific HIGHTAIL EXPRESS "Accept incoming network connections"

I am aware that this request is important for many applications.

On Hightail Express, I choose Decline when I'm asked to, and it seems to be working normally (but it's not great!). So I have allowed but no change to see. How do I find out exactly what makes admitting or rejecting?

By the way – If you search Google for "Hightail Express" to accept incoming network connections, almost nothing is displayed. Is that a stupid question?
