In some cases, when Central will launch (but still have issues with the installation due to permission issues) you can try using Settings > Maintenence > Fix Permissions and Ownership. within Central itself.
Even though the mentioned Sudo commands in this topic might solve a permission-related issue when using recent Mac OS computers and Waves Central, inserting a wrong Sudo command can potentially block your computer !!!
Tech Support will be able to verify the exact cause of the issue (since this is not always the same case when receiving a permissions-related error) and if required, perform the mentioned commands among other steps to solve the issue, these will be handled by an official Waves representative who is trained to solve Waves related errors.
Simply click on the next link and apply for technical assistance. Note that if required a Waves representative will be able to remote in to your computer in order to solve a permission-related issue.
Thanks this worked for me after a year of going round in circles with waves support.
the problem is the helper is disabled in services. you dont even have to run the sudo uninstall helper tool comand . just run the last line to enable the helper service.
{before the command } disabled services = {
“com.waves.central.InstlHelper” => true
{after the command} disabled services = {
“com.waves.central.InstlHelper” => false
