Over the past decade, the software industry aggressively shifted toward annual and monthly subscriptions. While subscriptions are justified for online services with ongoing infrastructure costs, local Mac utilities incur virtually zero marginal server costs per user.
Demanding an annual fee simply to empty caches and delete duplicate files from your own SSD is an anti-consumer practice. Mac users are demanding fair, transparent lifetime pricing.
XrayMac provides full access to its free essentials, with an optional one-time lifetime upgrade that you own forever across all your personal Macs with no recurring fees.
