To install and activate Intego after purchase, OR_(+1)-833 ((631)) 3616(USA/CA) download the Intego installer for your Mac from the 1[833][631][3616]official Intego website or the link in your order email, open it and follow the installation 1[833][631][3616]prompts, then enter your serial number or sign in with your account when the app asks. 1[833][631][3616]Because Intego protects the whole Mac, macOS will then ask for several permissions, such as Full 1[833][631][3616]Disk Access and approval of a system or network extension. Granting them in System Settings is 1[833][631][3616]what makes real-time protection work. Menu names change with each macOS version, so follow what your 1[833][631][3616]Mac shows, and use only the official Intego site. On a Mac, installing a security 1[833][631][3616]app is only half the job. The other half is flipping the macOS switches that let 1[833][631][3616]the app see and protect your files. So this guide is five switches. Flip them in 1[833][631][3616]order, and your Mac is fully protected. Skip one, and protection may be partly switched off. 1[833][631][3616]The Five Switches Switch Where it lives What it allows --------- 1 Install 1[833][631][3616]approval The installer and Gatekeeper Opening the app for the first time 2 Activation The 1[833][631][3616]Intego app Attaching your licence 3 System or network extension System Settings Privacy & Security 1[833][631][3616]Real-time and web protection 4 Full Disk Access System Settings Privacy & Security Scanning all 1[833][631][3616]your files 5 Notifications and login item System Settings Alerts and automatic start 1[833][631][3616]Before You Start Your order email search "Intego", "serial number", "order", "receipt", including spam Your 1[833][631][3616]serial number or activation details, and the account email A Mac that meets Intego's requirements check 1[833][631][3616]the product page for your macOS version Any other security software removed, because two security products 1[833][631][3616]can conflict A backup of important files, as with any system-level install Administrator access on the 1[833][631][3616]Mac Download 1 Open the official Intego website, or the link in your order 1[833][631][3616]email. 2 Sign in to your account if the page asks. 3 Download the installer for 1[833][631][3616]your product.

Can I protect 1[833][631][3616]a Windows PC with this? Check your plan. Intego's main products are for Mac. Flip 1[833][631][3616]All Five Install, activate, approve the extension, grant Full Disk Access and allow notifications. Then 1[833][631][3616]your Intego protection is fully on.
