General

Is there a difference between the Mac App Store (MAS) version and the non-MAS version?

Both versions have exactly the same features. Note that sometimes there are updates that fix an issue that only exists in one of the two versions, so the version number might be slightly different.

I have lost my license code.

Everyone who buys one of my apps within the app or on this website gets an email with a license code. Download the trial version and enter your email and license-key. If you cannot find the license code, please contact me via the support page. Note: If you have bought the app on the Mac App Store you do not need a license code. You can download the latest version directly from the purchases section on the Mac App Store.

I have bought an application on the Mac App Store, but it does not download.

You have probably downloaded the trial version from the website before. Delete every copy of the app you can find and then download the latest version directly from the purchases section on the Mac App Store. If you still have difficulties installing the app from the Mac App Store, please contact the Apple support.

PDF Squeezer

PDF Squeezer was unable to reduce the file’s size.

This is probably the case if the application that created the document already reduced the quality in order to reduce the size of a PDF document containing many pages and pictures. This can also happen if your PDF document contains no or almost no images. Your file may also contain vector graphics that look like (bitmap-)images. Vector graphics cannot be compressed.

Like all other PDF compression tools PDF Squeezer does not reduce the size of PDF files that have already been compressed.

Sometimes when I compress a file the images end up coming out color inverted in the compressed version.

Changing the color profile settings for the selected filter usually helps:

How can I open a PDF in PDF Squeezer from the print dialog ?

Due to Apple’s guidelines, PDF Squeezer cannot automatically install the PDF service that adds the Save PDF to PDF Squeezer to the print dialog. However you can use the PDF Print Service Creator app to for that.

How to enable the action plugin in Finder and Preview ?

Open the System Preferences and open the Extensions preferences pane. Then click Share Menu and check PDF Squeezer in the list. The plugin requires macOS 10.10 or later.

Network Radar

Why does Network Radar not display every information of a device ?

There might be one or several reasons for this:

If you perform a scan for devices outside the subnet of your Mac’s current network it is not possible to figure out the MAC address of these devices. Therefore information such as the vendor name are not available, too.

Certain network services are disabled or blocked within your network. Please contact your network administrator.

Some devices in your network or services of a device might be blocked by a firewall.

The device simply does not reveal certain information. I.e. there might be no NetBIOS name if SMB is not enabled on the device.

I performed a scan but Network Radar did not find all devices I expected.

Did you scan the correct IP range? Make sure that the devices you miss are turned on and connected to your network. Some devices such as smartphones often turn off their Wi-Fi in order to save energy if they are not being used. In most cases refreshing your scan helps.

I performed a scan and Network Radar found a device I cannot identify.

In rare cases Network Radar might find a not existing device. This is due to network irregularities. If you refresh your scan and that device keeps showing up as an offline device you can delete that device. These devices usually don’t have a MAC-address.

What does it mean if a device's status is uncertain?

Sometimes a device has an uncertain status shown by a yellow dot in the devices list. This simply means that Network Radar could not ping the device, but it is still in the ARP-Cache. So it was connected to that device recently.

What does it mean if a device's status is unreachable?

If the device's scan has been bound to a network and your Mac is not connected to that network, the device is unreachable. You won't be able to refresh the device's status. Also the device will be automatically excluded from monitoring.

Why did Network Radar find a MAC address, but no vendor name?

Network Radar looks up the vendor OUI (Organizationally Unique Identifier) of a MAC address in a local database. Devices that have MAC addresses, registered after the most recent release of Network Radar are not included in that database.

Remote Wake Up

How to wake up a Mac.

  1. Make sure the Mac you want to wake up is connected via Ethernet (wired connections). Wi-Fi does not work. USB to Ethernet or Thunderbolt to Ethernet adapters also work.
  2. Read How to enable WakeOnLAN on a Mac.
  3. Create a new host in Remote Wake Up and enter the Mac’s MAC address.

How to wake up a device that is not a Mac.

  1. Make sure the device you want to wake up is connected via Ethernet (wired connections). Wi-Fi does not work. USB to Ethernet or Thunderbolt to Ethernet adapters also work.
  2. Read How to enable WakeOnLAN on a device that is not a Mac.
  3. Create a new host in Remote Wake Up or edit an existing one and enter the the device’s MAC address.

How to shut down, restart or send a Mac to sleep.

  1. Read How to enable SSH on a Mac.
  2. Create a new host in Remote Wake Up or edit an existing one and enter the the Mac’s IP address and a SSH user name and password.

How to shut down, restart or send a PC to sleep.

You can only shut down, restart or send a device to sleep if it is a Mac running OS X.

How to wake up a device via the Internet.

If you want to control a device that is connected to a network outside your local network do the following:

  1. First, read how to configure a device in a local network.
  2. Find out your router’s external IP address or domain name.
  3. Configure your router to forward a UDP port (for WakeOnLAN) or TCP port (for SSH) to the device you want to control or to the network's broadcast IP (usually the last address of an network).
  4. Create a new host in Remote Wake Up or edit an existing one and enter the IP/domain and the WakeOnLAN or SSH port. You don’t have to enter a MAC address if you only want to control a device over the internet and forward the packets directly to the target device.
  5. Make sure you check the 'Send via Internet' box before you click the Wake Up button.

How to enable WakeOnLAN on a Mac.

  1. From the Apple menu, choose System Preferences.
  2. From the View menu, choose Energy Saver.
  3. Select (check) "Wake for network access". Note: The "Wake for network access" option's text may differ depending on the capabilities of your Mac:
    • Wake for network access - Your Mac supports Wake on Demand over both Ethernet and AirPort
    • Wake for Ethernet network access - Your Mac supports Wake on Demand over Ethernet only
    • Wake for Wi-Fi network access - Your Mac supports Wake on Demand over AirPort only. You won’t be able to wake up this device with Remote Wake Up.

How to enable WakeOnLAN on a device that is not a Mac.

That depends on the device. There is a good description for Windows and Linux based PCs on howtogeek.com.

PDF Protector

If I lock a document do i have to use PDF Protector to unlock it again?

PDF Protector uses standard encryption methods. Once your PDF document is locked you can unlock it with every standard PDF software such as Adobe Reader or Preview. It does not matter which application and operating system you use.

I have locked a PDF document and lost the password. How can I recover it?

PDF Protector locks and unlocks PDF documents, but you always need a valid password. PDF Protector does not crack passwords (assumed you know the password).

I have locked a PDF document and lost the password. How can I recover it?

You can set a password to protect your PDF files either from opening (User Password) or copying, printing and editing (Owner Password), or both. If a file has been encrypted with both the user and owner password you have to know the owner password in order to remove the encryption. Note that some software allows to remove an Owner Password without knowing it. However, it's not possible to remove a User Password. The User Password and the Owner Password has to be different.

Once I encrypt the file, can I send it to anyone so that they can open it?

Yes, any PDF reader should be able to read the encrypted files and ask for a password before showing it's content.

Screenshot Path

Is Screenshot Path available for download on the Mac App Store?

Screenshot Path is not available on the Mac App Store, but you can download it here.

After using Screenshot Path I get the following message when taking a screenshot:

This can happen if you deleted your screenshot folder. Use Screenshot Path to specify a new folder.
