Quickly fix Dropbox permissions errors in OS X

Dropbox is one of the more popular cloud-based syncing and storage tools, and offers Mac users a convenient way to transfer files from one system to another, or share files with colleagues. Dropbox can sometimes give you errors, saying that it cannot transfer something because it does not have permission to access some of the files being copied.

If this happens, then it could be because of an improper permissions setup with the Dropbox configuration files in your account, or with the files currently being copied.

If a permissions error such as this occurs, then the first thing that might … Read more

How to secure files from other users on external disks

If you use an external disk drive with OS X, you may notice that when it is mounted, it becomes available for all users on the system. Therefore, if you have files you have saved to a USB drive and you attach it to your system and you switch user accounts, those files will be viewable within the second account.

In addition, if you have network file sharing enabled, the files on this drive will be accessible to any user who logs in via the network.

This behavior may seem a bit concerning, especially for those who have set up … Read more

Solving read-only conditions for external hard drives

Do you have an external hard drive that you cannot write to on your Mac? While most external storage media's default formatting and other setups should make them both readable and writable on most Mac systems, there may be times when this is not the case.

NTFS formatting The first detail to check is if the drive is formatted to the popular NTFS format used in Windows systems. Often commercially available drives will be formatted to FAT32 and therefore be fully compatible with both Windows and OS X; however, many popular drives (especially high-capacity ones) may be formatted to … Read more

How to edit application permissions on BlackBerry 10

The first time you install a BlackBerry 10 app you're required to approve or deny the app access to various types of information on your device. For example, the Foursquare app requires permission to access your location (among other things) in order to find nearby venues. While other apps may request permission to access your photos, music or connect to BBM.

Denying an app permission to one of the requested categories is a good way to protect your personal data, but should you mistakenly deny an app permission, you'll need to know where to go to edit these … Read more

Fix permissions errors for sandboxed applications in OS X

When using some common sandboxed applications in OS X such as TextEdit, you may run into an issue where the program experiences file access errors for which you may not even receive a notification.

Some new Macs unable to reinstall Mountain Lion

An apparent issue in the versions of OS X that are preinstalled on Macs shipping from the factory is causing headaches for some users, where they may run into problems if they try to reinstall OS X or restore from a backup.

What to do if OS X asks for passwords when managing files

In OS X you should be able to create and manipulate files on your system largely without being burdened to authenticate, especially if the files are within resources your account owns such as your home folder. However, after upgrading or otherwise performing changes to the system you may find that the system continually prompts you for a password when you try to manage your files.

Sometimes this issue may occur only when you perform certain tasks such as deleting files (as opposed to placing them in the trash), but at other times it may happen on any manipulation.

OS X … Read more
