# ColorSyncProfileInstall(_:_:_:_:) Installs a profile in the specified domain. ``` func ColorSyncProfileInstall(_ profile: ColorSyncProfile!, _ domain: CFString!, _ subpath: CFString!, _ error: UnsafeMutablePointer?>?) -> Bool ``` ## Parameters `profile` The profile to install. `domain` The domain to install into, either [`kColorSyncProfileComputerDomain`](/documentation/ColorSync/kColorSyncProfileComputerDomain) or [`kColorSyncProfileUserDomain`](/documentation/ColorSync/kColorSyncProfileUserDomain). `subpath` A string created from the file system representation of the path of the file to contain the installed profile. `error` On failure, a pointer to an error describing the problem. Optional. ## Return Value `true` on success, or `false` in case of error. ## Discussion The `domain` is either [`kColorSyncProfileComputerDomain`](/documentation/ColorSync/kColorSyncProfileComputerDomain) or [`kColorSyncProfileUserDomain`](/documentation/ColorSync/kColorSyncProfileUserDomain). [`kColorSyncProfileComputerDomain`](/documentation/ColorSync/kColorSyncProfileComputerDomain) is for sharing the profiles (from `/Library/ColorSync/Profiles`). [`kColorSyncProfileUserDomain`](/documentation/ColorSync/kColorSyncProfileUserDomain) is for user custom profiles (installed under the home directory, that is, in `~/Library/ColorSync/Profiles`). `NULL` is the same as [`kColorSyncProfileUserDomain`](/documentation/ColorSync/kColorSyncProfileUserDomain). The `subpath` is the file system representation of the path of the file to contain the installed profile. The function interprets the last component of the path as a file name if it ends with the extension `.icc`. Otherwise, the function interprets the subpath as the directory path and creates the file name from the profile description tag, appended with the `.icc` extension. Using this function requires `COLORSYNC_PROFILE_INSTALL_ENTITLEMENT`. --- Copyright © 2026 Apple Inc.
